How Warmerly does it
Warmerly, in detail.
Warm the mailbox, then send from it.
01
Sequences
Email, wait, LinkedIn and branching steps in a list editor or a drag-and-drop canvas, with an AI opener step.
Warmerly product, checked 21 October 2026
02
Pre-launch checks
A readiness check blocks a launch with no usable step or sender, and warns about DNS problems and spam-style copy.

03
No cap on sends on paid plans
Starter, Growth and Agency send without a monthly meter. Each mailbox still sends inside its daily limit. Free is capped at 100 sends a month.

04
One reply inbox
Replies land in one inbox with LinkedIn replies. A genuine reply stops that lead's sequence by default.

05
Blocking errors and warnings are separate
A missing step, sender or lead blocks a launch. Content, DNS and sender identity problems only warn, and you confirm once to go on.

06
A sender is checked by plan
The launch check blocks a channel your plan does not include or a monthly cap that has been hit, which on Free is 100 sends.

07
Replies are matched by address
Replies are matched to a lead by address, because matching on headers alone caught only 15 of 95 replies in one case recorded in the code.

08
A reply stops the sequence
A genuine reply stops that lead's sequence by default, and a campaign setting can change that.
Warmerly product, checked 21 October 2026
09
The first send is gentle
A new campaign on young mailboxes opens at 3 emails per mailbox on day one, and the volume rises as warmup moves on.

Plain and AI openers
The plain three-step intro template has no AI opener and needs no brief, while the default cold intro uses an opener and needs one.

11
Free sends are capped
Free allows 100 campaign sends a month, which exists as an abuse guard and not as a trial clock.

What GlockApps does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- A campaign sender, sequence editor or reply inbox
- A sequence editor, scheduler or reply inbox
- How automatic tests are triggered from a sending tool
- Whether Gappie's campaign monitoring reads real campaign data
The numbers
Only what we could verify.
| Measure | Warmerly | GlockApps |
|---|---|---|
| Campaign sending | Sequences, pre-launch checks and one reply inbox, with no cap on sends on paid plans. | No campaign sender found; you send test messages through your own provider, relay or application. |
| Paid-plan send cap | No monthly cap | Not applicable, no sender |
| Free-plan sends | 100 campaign sends a month | Not applicable, no sender |
| Reply inbox | One, with LinkedIn | None found |
| Day-one volume on new mailboxes | 3 per mailbox | Not applicable |
| Launch gate | Blocking errors and one-time warnings | Not applicable |
In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Send first, then test
Use your sending tool as normal and run a GlockApps test on a copy of the message before a big send.
One tool or two
If you want warmup, sending and replies in one place, that is Warmerly. If you want a tester beside any sender, that is GlockApps.
Daily volume from mailboxes
If each of your 5 mailboxes sends 30 campaign emails a day, which is Warmerly's default daily limit, that is 150 a day. GlockApps does not set a send volume because it does not send.
Where a GlockApps test fits
Put the test between draft and launch. Copy the message, paste the ID, send to the seed list from the same provider you will use, read the report, then launch. A tester only answers the question for the message you sent.
Tests on a schedule
A Growth plan's automatic tests alert you when placement slips. That is a prompt to look at the mailbox, not a fix, and the fix still has to be made in whatever sends your mail.
Sending and testing on the same day
With 5 mailboxes sending 30 a day, a test of one message is 1 of 150 daily sends. A single result says little about the other 149, so test the message type, not the day.
