Spam rescue, in one look.

How Warmerly does it
Warmerly, in detail.
Every spam-placed warmup mail is recovered on a published delay, marked read, starred and important, moved to the inbox and answered.
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.

02
What a rescue does
It marks the message read, starred and important and moves it to the inbox. On Gmail, moving 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.

A reply follows
After a rescue a reply is queued unless the thread is at depth 3.

05
Unconditional, not sampled
Rescue used to apply to about three messages in four. It now applies to every spam-placed warmup message, because a message left in Spam keeps teaching the filter that the sender is junk.

06
Four folder names are checked
The processor looks in [Gmail]/Spam, Junk, Spam and Junk Email, which covers Gmail, Outlook and most other providers.

07
Junk flags are swapped first
Before the move it removes the Junk keywords and adds NotJunk keywords. Servers differ on which keywords they accept, so this step ignores errors and the move still happens.

08
Rescues are counted
A rescued job is stored as delivered to spam and opened, so it still counts in placement and rescue statistics rather than disappearing.

09
The reply does not wait on chance
A reply from the recipient is queued after a rescue whatever the account's usual reply probability. It is skipped at thread depth 3, when the recipient is not active or aging with warmup on, and for a hosted mailbox answering a low reputation sender.

A restoration claim

For content problems, a test
Where the cause is content or setup, it points to the spam test to find the triggers, and does not claim warm-up fixes those.

Starring is listed too
The how-it-works page lists opening, starring, marking as important, taking out of spam and replying positively as the interactions it creates.

Hidden from your mailbox
It says the warming emails are hidden from your own mailbox, so the rescued mail is not something you see or handle.

A help article on restoring reputation
Its help centre lists an article titled How to restore a bad sender reputation and fix a low score with MailReach. We read the title only, not the article.

What Mailreach 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 rescue takes
- What share of spam-placed warm-up mail is rescued
- How restoration is measured
- Whether a rescued message is also answered
- What the article on restoring reputation recommends
- Which folders it checks for spam placement
Where the sources disagree
We report each version rather than pick one.
- The 90% restoration figure sits on three of its pages without any sample or definition.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
A rescue helps warm-up mail, not yours
Both rescue warm-up messages between network mailboxes. Neither moves your campaign mail out of a prospect's spam folder.
Ask about the 90%
If restoration is why you are buying, ask Mailreach how it defines and measures the 90% it states.
When a rescue lands
A message that reaches a recipient's spam folder at 09:00 is not touched at 09:01. With a read delay of 10 to 120 minutes it is rescued some time between 09:10 and 11:00. A mailbox's very first warmup email is read within 10 to 20 minutes, so on day 0 the wait is at most 20 minutes.
What rescues look like at volume
A Gmail mailbox at its cap of 40 sends that places 5 messages in spam produces 5 rescues and, unless a thread is at depth 3, 5 queued replies. Because rescue is unconditional, the count of rescues equals the count of spam placements, which is also the figure the placement statistics use.
Judging the 90% claim
A rate of 90% could mean 9 mailboxes in 10 recovered, or 9 messages in 10 pulled out. The page says neither, and gives no sample or period. Ask for the denominator before you let it decide a purchase.
Your own campaign mail
If a prospect's filter sends your campaign email to spam, no warmup rescue reaches it on either tool. What helps there is sending in smaller batches from a healthy mailbox, and checking DNS and blocklists before you launch.

Questions
Does Mailreach rescue emails from spam?
Its pages say warm-up emails that hit spam are pulled out, and give no timing or method (read 21 October 2026).
How fast does Warmerly rescue a warmup email?
Each message has a read delay of 10 to 120 minutes, and a mailbox's first email is read after 10 to 20 minutes.
Does Warmerly rescue only some spam-placed warmup mail?
No. It used to rescue about 75% and now rescues every message, because leaving one in Spam teaches the filter the wrong thing.
Can a rescue move my campaign email out of a prospect's spam folder?
No. Only warmup mail between Warmerly mailboxes is rescued, and campaign mail to real prospects is never touched. Mailreach's pages describe rescue for its warming mail and say nothing that suggests otherwise.
Does Mailreach explain how restoration works?
It says volume can be raised strategically to repair a damaged reputation and that restoration is possible in 90% of cases, with no method (read 22 October 2026).
