Warmerly
Every spam-placed warmup mail is moved to the inbox after 10 to 120 minutes.
TrulyInbox
It says it moves warmup mail from spam to the inbox; no timing is given.
The short answer
Spam rescue, in one look.
Both pull warmup mail out of spam and mark it as wanted. Warmerly publishes its timing: a read delay of 10 to 120 minutes, and 10 to 20 for a mailbox's first email. TrulyInbox says it moves spam-placed mail to the inbox and stars it, and gives no timing for the rescue; its 45 to 400 second figure is the delay before a first open. Last checked 21 October 2026.

Warmerly's timings come from its warmup code. TrulyInbox's 45 to 400 seconds is the delay before a first open, not a rescue time.
How Warmerly does it
Warmerly, in detail.
A processor that finds any warmup mail in a recipient's spam or junk folder and moves it to the inbox, with a published delay.
01
Every spam-placed warmup mail
The processor recovers any warmup message found in a recipient's spam or junk folder. It never touches campaign mail to real prospects, which is a deliberate boundary.

What a rescue does
It marks the message read, starred and important, and moves it to the inbox. On Gmail, moving a message out of Spam is the Not spam signal.

03
When it happens
Each message has a read delay of 10 to 120 minutes, and the first email of a mailbox is read after 10 to 20 minutes. About 90 per cent of warmup mail is opened and about 20 per cent of opened mail is starred.

04
A reply follows
After a rescue a reply is queued unless the thread is already at depth 3, so a rescued message becomes part of a short conversation.

Counted in the health score
Where a warmup email landed is the largest part of a mailbox's health score, about half. A low score or high spam placement then cuts the warmup quota to 0.75, 0.7 or 0.4 of normal.

What it does not measure
A rescue is about warmup mail inside the network. It says nothing about where your real campaign emails land, which is what a placement test is for.

How TrulyInbox does it
TrulyInbox, in detail.
Rescue is listed as one of eight daily background actions, with no timing, and its help centre spends more words on why mail lands in spam than on the rescue.
01
One of eight daily actions
How it works lists what runs each day: it moves emails from spam into the primary inbox, sends contextual replies, stars or marks emails as important, checks blacklists, sends at varied intervals, creates unique content, tailors it to your industry, and prioritises warmup across providers.

02
The 45 to 400 second delay
A help article says the first action on a warmup email, such as opening it, might happen after a random delay of 45 to 400 seconds, given as an example. After that the system may open, star or reply, each timed and randomised.

03
How deliverability is read
A help article defines deliverability percentage as the share of your sent emails that reach other users' primary inboxes, as a ratio of inbox to spam. Received emails do not affect it, and the article does not explain why a mailbox can show 100%.

04
Why mail still lands in spam
Its help says most spam placement during warm-up is caused by behaviour, not content: sudden volume jumps, parallel outreach in the first two to three weeks, frequent pauses and restarts, and interfering with warm-up such as deleting emails.

05
What to do when it happens
The same article says that if emails land in spam you should not raise volume or start campaigns, and should review recent changes and let sending stabilise. It adds that warm-up does not guarantee instant inbox placement.

Inbox, not spam, in the score
The warmup score treats inbox placement as raising the score and spam placement as lowering it, over the last 15 active days. No relative weighting between the two is given.

What TrulyInbox does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- How long a message stays in spam before it is moved
- Whether every spam-placed warmup email is rescued, or a share of them
- What the 100% deliverability case means, which its own article leaves unexplained
- Whether rescue ever touches mail that is not warmup mail
Where the sources disagree
We report each version rather than pick one.
- TrulyInbox's article on deliverability percentage defines it as inbox against spam in one sentence and as the share landing in the primary inbox in another. Those are different ratios, and the article does not choose.
- Its how-it-works page presents automated replies and marking as important as part of the product, while its terms put the responsibility for checking your provider's terms on you.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Do not compare 45 seconds with 10 minutes
TrulyInbox's 45 to 400 seconds is when a first action may happen on a warmup email, not when a rescue happens. Warmerly's 10 to 120 minutes is the delay before a message is read, rescued or not. They measure different things.
A fast rescue is not automatically a good one
Moving mail out of spam within seconds would look robotic. Warmerly's spread of 10 to 120 minutes is a design choice to look human, and TrulyInbox says its timing is randomised for the same reason.
Read your provider's terms
Marking mail as not spam, starring it and replying are automated actions on a real mailbox. TrulyInbox's terms say you are responsible for making sure your email provider's terms allow automation services, and the same applies to Warmerly.
Rescue shows the symptom, not the cause
If warmup mail keeps landing in spam, TrulyInbox's advice is to look at volume, parallel tools and recent changes. Warmerly's health score and DNS checks are where we would look for the cause.
Watch the score, not one message
One rescued email is not a trend. Both products turn inbox and spam outcomes into a score over days, and the score is the thing to follow.
Who it suits
Pick the one that fits.
Warmerly
Warmerly is the better fit if
- You want a published rescue delay and the rule that campaign mail is never touched
- You want a rescued message to be followed by a threaded reply
- You want spam placement to feed a score and reduce volume by itself
- You want the boundary between warmup mail and real mail stated
TrulyInbox
TrulyInbox is the better fit if
- You want spam rescue described alongside a list of the other daily actions
- You want help articles on why warmup mail lands in spam
- You want to read deliverability as an inbox share of sent mail
- You are happy with a rescue that has no stated timing
Questions
Does TrulyInbox rescue emails from spam?
Yes, per its how-it-works page: it moves emails from spam into the primary inbox as one of eight daily actions. It gives no timing for the move.
How fast does Warmerly rescue a message?
A read delay of 10 to 120 minutes applies to each warmup message, and 10 to 20 minutes for a mailbox's first email. Rescued mail is marked read, starred and important.
Does either tool rescue my campaign emails?
Warmerly states it never touches campaign mail to real prospects. TrulyInbox does not say, and we found no campaign mail in its product.
Why do warmup emails land in spam at all?
TrulyInbox's help puts most of it down to behaviour: sudden volume jumps, parallel outreach, restarts and tampering. Warmerly's checks also look at DNS records and blocklists.
What is the 45 to 400 second delay at TrulyInbox?
It is the example delay before a first action such as opening a warmup email, not a rescue time.
