The short answer
Editorial assessmentTrulyInbox compared with GlockApps
These are complements rather than competitors, and confusing them is a common and expensive mistake. GlockApps measures where mail lands using a documented seed panel and monitors blacklists and DMARC, with no warming. TrulyInbox warms mailboxes and never tests real placement. A serious outbound operation runs one of each.
Choose GlockApps if
Email marketers, ESP-side deliverability teams, and consultants who need to prove and diagnose inbox placement across providers, run DMARC reporting at scale, and monitor reputation continuously, without paying for warm-up or sending infrastructure they already have elsewhere.
Choose TrulyInbox if
Outbound teams and agencies running ten or more sending mailboxes who want warming priced by volume rather than per seat, with API access to automate mailbox provisioning.

| Setup time | Under an hour to run a first seed test; DMARC Analytics requires a DNS record change (pointing the RUA tag) that can take up to 24-48 hours to start receiving reports depending on receiver reporting schedules. | Fifteen minutes to connect mailboxes and start warming. Three to six weeks of ramping before a mailbox is ready for real sending volume, which is the actual timeline and cannot be shortened by spending more. |
| Learning curve | Low for running a seed test and reading inbox/spam placement; moderate for interpreting DMARC aggregate data and spam-filter scoring without prior authentication knowledge. | Low to operate, higher to use well. The configuration surface is larger than most warming tools, with four strategies, reply rates, schedules, and topic control, and the temptation is to turn everything up. Aggressive settings make traffic look less like correspondence, not more. |

Strengths and limitations
GlockApps
Strengths
- Broad seed-list panel (70+ addresses across Gmail, Outlook, Yahoo, corporate) gives a credible cross-provider placement read for the price.
- DMARC Analytics is a full-featured report parser on its own, competitive with dedicated DMARC-only tools, and the free tier's 10,000 messages/month is genuinely usable for small domains.
- Blacklist and DNS-record monitoring catch infrastructure problems (a broken DKIM key, a new blacklisting) before they show up as a placement drop.
- Gmail tab prediction addresses a specific, common blind spot that plain inbox/spam scoring misses.
Limitations
- No native warm-up or sending capability; a separate G-Lock-affiliated product (WarmupIP) handles warming under its own brand, so buyers expecting one bundled subscription for testing and warming will need a second tool and a second bill.
- Seed tests measure a fixed panel of test inboxes, not your actual recipient list; results are a strong proxy, not proof of how any individual subscriber's mailbox will filter a message.
- Interface and reporting design read as dated next to newer entrants, functional but not polished.
- Free tier's 2 test credits are too thin to evaluate the product's core value without upgrading.
TrulyInbox
Strengths
- Volume-based pricing with unlimited accounts on every paid tier, which makes cost predictable while the sending estate churns.
- Effective per-mailbox cost falls as you scale, reaching around $3.40 a mailbox at fifty, cheaper than most per-seat competitors.
- API access from the $22 entry tier, where most of the category treats it as an enterprise feature.
- Four warming strategies with fine-tuning and configurable reply rates, which is more control than most warming tools expose.
Limitations
- Automated warming is contested practice. It manufactures engagement that does not reflect real correspondence, providers have improved at detecting reciprocal warming networks, and Google has publicly discouraged it. Use it to ramp genuinely new mailboxes, not to rescue unwanted campaigns.
- Network composition and quality cannot be independently verified by a buyer, here or at any warming vendor.
- No seed-list inbox placement testing, so the deliverability score reflects placement of warming traffic inside the network rather than placement of your real campaigns with real recipients.
- No DMARC report monitoring or authentication management of any kind.
Pricing compared
GlockApps
Tiered monthly or annual subscription metered on Inbox Insight test credits and DMARC message volume, with a free tier and per-tier overage pricing above the included message allowance.
- Free$0
- Essential$59
- Growth$99
- Enterprise$129
GlockApps is priced fairly for what it is: a diagnostics and monitoring subscription, not a fix. $59-99/month buying seed testing across 70+ addresses, full DMARC reporting, and blacklist monitoring is cheap relative to hiring a consultant to do the same work manually, and cheaper than most warm-up suites that bundle a thinner placement-testing feature. The catch is that none of it repairs anything: a team that finds a domain in spam through GlockApps still needs a separate warmer, a DMARC policy change, or a blacklist delisting request to act on the finding, so budget it as the measurement layer, not the whole deliverability line item.
TrulyInbox
Freemium subscription priced by total daily warmup email volume, with unlimited connected email accounts on every paid tier.
- Free$0
- Starter$22
- Growth$84
- Scale$169
- Scale PlusFrom $407
The volume model is the whole argument, and it is a good one above roughly ten mailboxes. Fifty mailboxes for $169 a month at around $3.40 each undercuts per-seat competitors, the bill stays constant as the estate churns, and API access at the entry tier means an outbound stack can provision warming automatically. Below ten mailboxes the maths reverses and InboxDoctor's $2 to $6 per mailbox is cheaper. What you do not get at any tier is seed-list placement testing, so the deliverability score you see reflects where warming mail lands inside the network rather than where your campaigns land with real recipients, and that distinction matters more than the price difference between vendors.
Editorial verdict on each
GlockApps
Best ValueGlockApps is the sharpest diagnostics-and-monitoring buy in the category for teams that already have a sender and just need to know, with evidence, where mail is landing and why. Seed testing across 70+ addresses, full DMARC reporting, and blacklist monitoring at $59-99/month undercut most warm-up suites' bundled testing features while going deeper on each one. The tradeoff is real: nothing in GlockApps fixes what it finds, so a team expecting one subscription to both diagnose and repair deliverability will end up buying a second tool anyway. Budget it as the measurement layer of a deliverability stack, not the whole stack.
Read the full GlockApps profileTrulyInbox
TrulyInbox is the warming tool to buy if you run a lot of mailboxes or a sending estate that changes every month. Pricing by daily volume with unlimited accounts keeps the bill flat while mailboxes come and go, the effective cost falls to around $3.40 a mailbox at fifty, and API access from the $22 entry tier makes automated provisioning practical in a way most competitors reserve for enterprise contracts. The configuration depth, four ramp strategies and adjustable reply rates, is real and should be used conservatively rather than turned up. Two things temper the recommendation. Below ten mailboxes, per-mailbox vendors are simply cheaper. And there is no seed-list placement testing at any tier, so the deliverability score tells you about warming traffic inside a network that is designed to like you, not about your campaigns reaching strangers. Pair it with a placement tester, keep the honest caveat about warming as contested practice in view, and it is a well-shaped product for exactly one job.
