## Overview

Mailmeteor is what happens when a mail-merge tool is designed by people who care about restraint. It is a Google Workspace add-on rather than a browser extension, it reads the Google Sheet you point it at, and it sends from your own mailbox with an interface clean enough that non-technical staff can use it without training. The company's stated principle is privacy: it positions itself as not reading your emails or mining your contacts, which is an unusual thing to lead with in a category where most vendors lead with volume.

The pricing is the other thing that stands out. A genuinely usable free tier gives you 50 emails a day and 500 a month with templates, tracking, scheduling, and attachments. Starter at $5.99 per user per month raises that to 250 a day and 5,000 a month and adds email verification, reply detection, shared templates, Zapier, and branding removal. Premium at $17.99 gets you 1,000 a day, 30,000 a month, follow-up sequences, an AI assistant, a custom tracking domain, and warm-up. Professional at $35.99 adds inbox rotation, 2,000 a day, 60,000 a month, and team analytics. Nothing in this category is cheaper per email at these volumes.

The company is Paris-based, founded in 2018 by Corentin Brossault and Jean Cuireuncroco after meeting at STATION F, and deliberately bootstrapped. It describes itself as fiercely independent and aiming for a long-term profitable business rather than a growth story, which shows in the product: the feature list moves slowly, the interface stays uncluttered, and lifetime plans were discontinued in December 2024 in favor of a straightforward subscription.

The honest caveat is scope. Mailmeteor is a mail-merge tool that has grown cold-email features, not a cold email platform that happens to work in Gmail. There is no unified team inbox, no lead database, no multichannel steps, and the sending ceiling is Gmail's, split across whatever mailboxes you connect. For a small business sending a few thousand thoughtful emails a month, that is exactly right. For an outbound machine, it is not the shape of tool you need.

## How it works

1. You install the Mailmeteor add-on for Google Workspace, which appears inside Google Sheets and Gmail. There is also a standalone web app and an Excel path for people whose lists do not live in Sheets.

2. Your spreadsheet becomes the campaign: one row per recipient, one column per merge field. Mailmeteor previews each personalized message so you can see exactly what a given row will receive before anything sends, which catches the broken-merge-field problem that embarrasses people in this category.

3. You compose from a template or write directly, insert merge tags, attach files, and schedule the send. Mailmeteor paces delivery within your Gmail account's limits and within your plan's daily cap, and on paid tiers it verifies addresses first so bounces do not damage the mailbox.

4. After sending, tracking runs on your own custom domain from the Premium tier, results write back into the spreadsheet and the dashboard, and reply detection stops follow-up stages for anyone who has answered. Autopilot and Sheet Automations trigger sends from spreadsheet changes, Zapier covers the rest, and Professional adds inbox rotation across multiple connected mailboxes plus team-level analytics.

## Best for

Small businesses, schools, nonprofits, and lean teams that need personalized bulk email from their own Gmail account, want a free or single-digit-dollar option, and value a clean privacy-conscious tool over a maximalist outbound platform.

## Not the right fit for

- High-volume outbound operations; even Professional caps at 2,000 a day and 60,000 a month per user, which is a fraction of what a rotation-native platform does before breakfast.
- Teams that need a shared reply inbox with owners, statuses, and pipeline stages; Mailmeteor hands replies back to Gmail and stops there.
- Anyone who needs a built-in lead database or email finder; Mailmeteor sends the list, it does not build it, so pair it with Hunter, Snov.io, or your own research.
- Microsoft 365 shops wanting native Outlook sending; the product is built around Gmail, Google Sheets, and Google Workspace.
- Multichannel sequences with LinkedIn or calling steps, which Mailmeteor has no interest in and no roadmap for.

## Features

### Spreadsheet-native mail merge

The core loop, and the part that is genuinely better than competitors.

- **Google Sheets as the campaign source**: Every column becomes a merge field and results write back into the sheet, so the campaign, the list, and the reporting live in one document your team already knows how to edit.
- **Excel and CSV support**: For teams whose lists do not live in Google, Mailmeteor accepts Excel files rather than forcing a migration into Sheets.
- **Per-recipient preview before send**: You can inspect the exact message any individual row will receive before anything leaves, which is the single best defence against a merge field failing across two thousand recipients.
- **Templates and shared team templates**: Save and reuse message templates; Starter and above allow sharing them across a team so everyone sends the approved version.
- **Attachments**: Files can be attached to merged campaigns, including on the free tier, which many competitors gate behind a paid plan.
- **Scheduling**: Campaigns can be queued for a future date and time rather than sent the moment you finish writing.

### Sending model and limits

Everything hangs off your own Gmail mailbox, with plan caps layered on top.

- **Sends from your real mailbox**: Mail leaves through your authenticated Gmail or Google Workspace account rather than an SMTP relay, so reputation accrues to your own domain instead of a shared pool.
- **Published daily and monthly caps**: 50 a day and 500 a month free, 250 and 5,000 on Starter, 1,000 and 30,000 on Premium, 2,000 and 60,000 on Professional. The caps are stated plainly, which is rarer in this category than it should be.
- **Inbox rotation**: Professional distributes a campaign across multiple connected sending accounts, which is the feature that turns Mailmeteor from a mail-merge tool into something usable for real outbound.
- **Email warm-up**: Included from the Premium tier rather than sold as a separate subscription, which materially changes the total cost of running a new domain.
- **Custom tracking domain**: From Premium, open and click tracking runs through your own domain instead of shared vendor infrastructure that filters already recognize.
- **Autopilot and Sheet Automations**: Trigger sends from spreadsheet changes so recurring outreach runs without anyone opening the tool; five automations on Premium, more on Professional.

### Follow-ups, replies, and list hygiene

The cold-email layer bolted onto a mail-merge core.

- **Automated follow-ups**: Up to five follow-up stages on Premium and above, sent on the original thread and stopped automatically when someone replies.
- **Reply detection**: Available from Starter. Replies are recognized so sequences halt for that recipient rather than nagging someone who already answered.
- **Built-in email verification**: Included from the Starter tier, which removes a separate verification subscription for teams sending modest volumes.
- **Bounce and unsubscribe tracking**: Bounces and opt-outs are recorded against the campaign and written back to the sheet, and unsubscribe links are inserted so opt-outs are honored automatically.
- **Auto labels**: Premium files campaign mail and responses under Gmail labels so a large send does not make your primary inbox unusable.
- **Branding removal**: The free tier appends Mailmeteor branding to outgoing mail; every paid tier from $5.99 removes it, which matters for anything client-facing.

### Tracking, AI, and reporting

Modest by platform standards, sufficient for the buyer.

- **Open and click tracking**: Available on every tier including free, with results visible in the dashboard and written back into the spreadsheet.
- **AI email assistant**: From Premium, generates and rewrites message copy inside the composer rather than sending you to a separate tool.
- **Team analytics**: Professional adds aggregate reporting across users so a manager can see campaign performance beyond their own sends.
- **Campaign dashboard**: A web dashboard tracks campaigns across sheets, which is useful once you are running more than a couple of recurring sends.

### Privacy, platform, and integrations

The company's actual differentiator.

- **Privacy-first positioning**: The vendor states it does not read your emails or harvest your contacts, and the product deliberately does not ship a lead database built from user data. For a French company selling to EU buyers, this is a substantive stance rather than marketing.
- **Google Workspace add-on distribution**: Installs through the Workspace Marketplace with Google's own OAuth review, which is an easier conversation with an IT administrator than a third-party browser extension.
- **Zapier integration**: Available from Starter, connecting campaigns to CRMs, forms, and whatever else the business runs.
- **Multi-currency billing**: Priced in USD, EUR, and INR, which is a small thing that removes a real friction for non-US buyers.

## Use cases

- **Founder doing careful low-volume outreach**: Two hundred well-researched prospects a month, where a generic blast would waste the research. Outcome: A Google Sheet holds the research columns, per-recipient preview confirms every message reads like a personal note, and Starter at $5.99 covers the entire month with verification and reply detection included.
- **School or nonprofit sending parent and donor updates**: Personalized mail to a few hundred people, no budget, and staff who will not learn a marketing platform. Outcome: The free tier handles 500 a month from the organization's own Gmail with templates, attachments, and tracking, and the interface is close enough to Sheets that nobody needs training.
- **Small agency running client outbound at modest volume**: Three thousand sends a month across two mailboxes with a client who will notice vendor branding. Outcome: Premium at $17.99 removes branding, adds warm-up, a custom tracking domain, and five follow-up stages, and Sheet Automations keep recurring campaigns running without manual launches.
- **Sales team of four graduating from manual sends**: Everyone is copying and pasting from a shared doc, follow-ups get forgotten, and nobody can see aggregate results. Outcome: Professional gives each rep inbox rotation, 2,000 a day, shared templates, and team analytics for $35.99 a seat, which is less than a single seat on most sales engagement platforms.

## Pricing

Per-user subscription with a real free tier; plans meter emails per day and per month rather than contacts or mailboxes, with feature gating on follow-ups, warm-up, tracking domains, and inbox rotation.

- **Hobby**: $0 per user per month. 500 emails per month, 50 per day; Email templates and scheduling; Open and click tracking; Attachments; Gmail, Google Sheets, and Excel support. Genuinely usable rather than a demo, but the Mailmeteor footer rules it out for client-facing work.
- **Starter**: $5.99 per user per month. 5,000 emails per month, 250 per day; Reply detection and email verification; Autopilot and shared templates; Zapier integration; Mailmeteor branding removed. The cheapest credible cold email plan on the market, and enough for most solo senders.
- **Premium**: $17.99 per user per month. 30,000 emails per month, 1,000 per day; Five follow-up stages and five Sheet Automations; Email warm-up included; Custom tracking domain; AI email assistant and auto labels. Where warm-up and a custom tracking domain arrive, which is where the product becomes safe for real cold outreach.
- **Professional**: $35.99 per user per month. 60,000 emails per month, 2,000 per day; Inbox rotation across connected accounts; Team analytics; Dedicated onboarding; Priority support. Inbox rotation is the only reason to go past Premium.

Billing notes:

- Annual billing gives three months free, which takes Starter to roughly $4.49 a month equivalent and Premium to about $13.49.
- Pricing is per user per month and quoted in USD, EUR, or INR; taxes are added at checkout.
- Lifetime plans were discontinued in December 2024, so anyone comparing against old lifetime-deal coverage is reading stale information.
- Custom pricing is handled by sales above 50 users, but everything below that is self-serve with no call required.
- Volume is metered per user, so a second sending mailbox generally means a second seat rather than a free connected account, which is the opposite of the GMass model.

Value assessment: At 10,000 emails a month Mailmeteor is the cheapest serious option in the category: one Premium seat at $17.99 covers it with warm-up, a custom tracking domain, follow-ups, and an AI assistant included, against $30 to $80 for comparable platform tiers. At 100,000 a month the model stops working; you would need two Professional seats at $35.99 just to reach 120,000 across two users, and the per-mailbox daily caps mean you are managing seats rather than mailboxes. That is the honest boundary: superb value up to roughly 30,000 sends a month, structurally wrong above 60,000.

## Strengths

- The cheapest credible paid tier in the category at $5.99, and a free plan that is actually usable rather than a teaser.
- Warm-up and a custom tracking domain are bundled from $17.99, which is a lower price for those two things than most standalone warm-up tools charge on their own.
- Per-recipient preview before sending is the best guard against merge-field disasters that any tool here offers.
- Spreadsheet-native workflow means non-technical staff can run campaigns without learning a new application.
- Privacy-first positioning from a Paris-based bootstrapped company, with no lead database built from user data, which is an easier story to tell an EU buyer.
- Daily and monthly caps are published plainly per tier instead of hidden behind fair-use language.
- Distributed as a Google Workspace add-on with Google's OAuth review, which passes IT scrutiny more easily than a browser extension.

## Limitations

- Volume ceilings are low: 60,000 a month per user on the top tier, which no high-volume outbound program can live inside.
- Inbox rotation only arrives at $35.99 Professional, and extra sending capacity generally means extra seats rather than free connected accounts.
- No unified team inbox; replies are handled in Gmail with labels, so there is no shared queue, no assignment, and no pipeline view.
- No lead database or email finder, so list building is entirely a separate purchase and a separate workflow.
- Google-centric by design, with no native Microsoft 365 sending path.
- Email only, with no LinkedIn, SMS, or calling steps, and no plan to add them.
- Feature velocity is deliberately slow; a bootstrapped four-figure-price product does not ship what a venture-funded competitor ships in a quarter.

## Comparisons

- **Mailmeteor vs GMass**: The two Gmail-native tools, split by philosophy. GMass is denser and more cold-email-native, with a Gmail-search list builder, free verification, an API, and free secondary accounts under MultiSend at $59.95. Mailmeteor is cheaper, cleaner, includes warm-up from $17.99, and is far easier to hand to a non-technical colleague. Choose GMass for power and multi-mailbox outbound; choose Mailmeteor for tidy, affordable, privacy-conscious merges.
- **Mailmeteor vs Hunter Campaigns**: Hunter sells data with sequencing attached; Mailmeteor sells sending with no data at all. If you cannot find the addresses, Hunter's database and verifier are worth its higher price. If you already have a spreadsheet of people, Mailmeteor sends to them for a fraction of the cost with warm-up and follow-ups included.
- **Mailmeteor vs Woodpecker**: Woodpecker meters contacts and targets deliberate agency outreach with strong deliverability engineering, a team inbox, and real reply management, at several times the price. Mailmeteor meters emails and stops at the spreadsheet. Agencies managing multiple client campaigns should pay for Woodpecker; a single small business sending a few thousand a month should not.
- **Mailmeteor vs Emelia**: Both are European, both are cheap, and both keep the interface small. Emelia is a proper web-app sequencer with LinkedIn steps, unlimited email accounts, and warm-up on low-cost plans. Mailmeteor is a Sheets add-on with lower volumes but a better merge workflow and a free tier. Take Emelia if you want a real outbound tool at a European price; take Mailmeteor if the spreadsheet is the point.
- **Mailmeteor vs Mailshake**: Mailshake is a per-seat sales engagement tool with a lead catcher, team inbox, and multichannel tasks, at roughly three to five times Mailmeteor's price. Mailmeteor has none of that and does not pretend to. Sales teams that need shared pipeline management take Mailshake; individuals and small non-sales teams sending personalized mail take Mailmeteor.
- **Mailmeteor vs Saleshandy**: Saleshandy connects unlimited email accounts with bundled warm-up and a lead database on plans in the $25 to $40 range, which is a genuinely different scale of product for a similar Premium-tier price. Mailmeteor counters with a free tier, a $5.99 entry point, and a simpler tool. Anyone whose plan involves more than about four mailboxes should look at Saleshandy first.

## Implementation

- Setup time: Under fifteen minutes. Install the Workspace add-on, open a Google Sheet, map columns, preview a row, and send. Custom tracking domain setup on Premium adds one DNS record.
- Learning curve: The lowest in this category. If someone can use Google Sheets they can run a Mailmeteor campaign, and the per-row preview means mistakes are visible before they are expensive.
- Onboarding: Fully self-serve up to fifty users; Professional includes dedicated onboarding and priority support. No implementation fee at any tier and no sales call required to buy.
- Migration: Lists are already spreadsheets, so there is nothing to migrate on the data side. Sequences are short enough to rewrite by hand. Because sending happens from your own mailbox and results write back into your own sheet, almost nothing is locked inside the vendor, though historical campaign analytics do not export into another tool's reporting.

## Platform, API & security

- Platforms: Google Workspace add-on for Gmail and Google Sheets, Web app, Excel support, Chrome extension
- API: No broad public REST API is marketed to end users; automation runs through Zapier, Autopilot, and Sheet Automations from the Starter and Premium tiers.
- Compliance: GDPR-aligned processing from an EU-headquartered vendor, CAN-SPAM tooling including unsubscribe links and opt-out suppression, Google Workspace Marketplace OAuth review for Gmail and Sheets scopes
- Data residency: European company headquartered in Paris; check the current data processing agreement for the exact hosting region before assuming EU-only storage.
- SSO: Google sign-in, since the product authenticates through the Google account itself. No SAML SSO advertised.
- Security notes: Mailboxes connect through Google OAuth rather than stored credentials, and mail sends through Google's own infrastructure rather than a third-party relay. The vendor's public position is that it does not read message content or harvest contact data, and it notably does not sell a lead database assembled from customer information.

## Support

- Channels: Email support on all tiers, Priority support on Professional, Dedicated onboarding on Professional
- Documentation: Documentation and a large help center covering mail merge, Sheets integration, deliverability, and Gmail sending limits, plus an active blog aimed at Google Workspace users.
- Community: Large Google Workspace Marketplace user base; no official forum.

## FAQ

### What is Mailmeteor?

Mailmeteor is a Gmail mail-merge and light cold outreach tool distributed as a Google Workspace add-on. You point it at a Google Sheet or Excel file, it personalizes a message per row, and it sends from your own Gmail or Workspace mailbox with tracking, scheduling, follow-ups, reply detection, warm-up, and inbox rotation depending on tier.

### How much does Mailmeteor cost?

There is a free Hobby plan with 500 emails a month and 50 a day. Starter is $5.99 per user per month for 5,000 a month, Premium is $17.99 for 30,000 a month, and Professional is $35.99 for 60,000 a month. Annual billing gives three months free. Lifetime plans were discontinued in December 2024.

### How many emails can I send with Mailmeteor?

The caps are published per tier: 50 a day and 500 a month on free, 250 and 5,000 on Starter, 1,000 and 30,000 on Premium, and 2,000 and 60,000 on Professional. Those are per user, and Google's own mailbox limits sit underneath them, so a consumer Gmail account will hit Google's ceiling before Mailmeteor's on the higher plans.

### Does Mailmeteor include email warm-up?

Yes, from the Premium tier at $17.99 per user per month. That is unusually cheap for bundled warm-up, since standalone warm-up services often cost more than that on their own. The free and Starter tiers have no warm-up, so new domains should start on Premium.

### Does Mailmeteor support inbox rotation?

Yes, on the Professional tier at $35.99 per user per month, which distributes a campaign across multiple connected sending accounts. Below that tier you are sending from a single mailbox, which is fine for a few hundred emails a day and not fine for a real outbound program.

### Does Mailmeteor use an SMTP relay?

No. It sends through your authenticated Gmail or Google Workspace mailbox, so reputation accrues to your own domain rather than to a shared relay pool. That is the same architecture GMass uses and it is the reason both tools inherit Google's daily sending limits.

### How does Mailmeteor handle unsubscribes, bounces, and GDPR?

Unsubscribe links are inserted and opt-outs are honored automatically, and bounces are tracked back into the spreadsheet and the campaign report. The company is Paris-based and positions itself as privacy-first, stating that it does not read your emails or harvest your contacts, and it notably sells no lead database. That covers the processor side. The lawful basis for contacting an EU individual, normally a documented legitimate-interest assessment plus a working opt-out, is still your responsibility as the sender.

### Does Mailmeteor have an API?

There is no broad public REST API marketed to end users. Automation runs through Zapier from the Starter tier and through Autopilot and Sheet Automations on Premium and above, which trigger sends from spreadsheet changes. If you need programmatic campaign control, GMass or a platform like Smartlead is a better fit.

### Is Mailmeteor good for cold email or just for mail merge?

Both, within limits. From the Premium tier it has the things cold email actually requires: follow-up sequences, reply detection, verification, warm-up, and a custom tracking domain. What it lacks is scale and reply management, so it works well up to roughly 30,000 emails a month from one or two mailboxes and stops being the right tool above that.

### Who owns Mailmeteor?

It was founded in 2018 in Paris by Corentin Brossault and Jean Cuireuncroco and is bootstrapped with no disclosed outside investment. The company describes itself as fiercely independent and aiming for long-term profitability rather than growth at any cost, which is visible in the slow, careful feature cadence.

## Editorial verdict

Mailmeteor is the best cheap tool in this category and one of the few that is honest about its ceiling. For a small business sending up to about 30,000 personalized emails a month from one or two Gmail mailboxes, $17.99 a seat buying warm-up, a custom tracking domain, follow-ups, verification, and an AI writer is unbeatable value, and the spreadsheet-native workflow means anyone on your team can run it. The free tier is real, the privacy stance from a bootstrapped Paris company is credible, and the per-row preview prevents the mistake everyone else makes. Buy it if the spreadsheet is your source of truth and your volume is modest. Do not buy it if you plan to run ten mailboxes, need a shared reply inbox, or run on Microsoft 365; those are structural mismatches, not gaps that a higher tier fixes.
