Every Inbox,Fully Warmed Up.
Connect your existing inbox and Unifers builds sender reputation for you — gradually increasing volume within limits you control, so you don't have to manage it by hand.

You set the pace.
Set limits on how many warmup emails go out daily or per campaign — Unifers handles the sending automatically, within the limits you choose.
Daily Send Limits
Cap how many warmup emails go out each day, so volume never scales faster than you want it to.
Per-Campaign Limits
Set separate limits for each campaign or inbox.
Adjust Anytime
Raise or lower your limits as your domain's reputation builds.
From zero reputation to fully warmed up.
A typical ramp, within the limits you've set. Most domains are fully warmed up in 4–6 weeks total — longer if the domain has a history of being flagged (a “burned” domain).
- Day 1
Connect your inbox
Warmup starts at low volume, within your set limits.
Volume increases
Within your limits; first deliverability signals appear on your dashboard.
Day 7- Day 14
Engagement builds
Steadily; your warmup health score becomes a reliable signal.
Reputation established
Well established for most domains; warmup continues if needed.
Day 21- week 4–6
Beyond day 21
Full warmup typically completes by week 4–6. Previously burned domains may take longer.
Everything runs on its own.
Once you connect an inbox, Unifers handles the ramp, the cleanup, and the recovery — automatically.
Automated scheduling
Volume ramps up automatically within the limits you set — no manual tuning day to day.
Real inbox network
Warmup runs on real email inboxes, not bots or a synthetic network, exchanging genuine opens, replies, and clicks.

If a warmup message lands in spam, Unifers pulls it out and marks it as important automatically, reinforcing to inbox providers that you're a trusted sender.

Track your inbox's readiness in real time as it moves toward fully warmed up.
