Problems we fix / Deliverability
Your emails are landing in spam.
Most spam problems start with the list and the sending setup, and both can be fixed.
B2B contact data decays by about 2% a month. A list verified three months ago is already around 6% dead, which is enough to push you past the bounce limits inbox providers watch.
How we fix each one
The list went stale before it was sent
Every address re-verified in two passes, never older than 21 days when it’s sent
Catch-all addresses sent like any other
Catch-alls split by mail provider: Google in, Microsoft capped in its own group, unknowns left out
Nobody sees the real bounce rate
A bounce inbox for each sending domain, checked weekly against the provider’s own logs
One blocklist hit takes everything down
Blocklists checked daily, inbox placement tested weekly and a reserve set of inboxes ready to switch to

“Half our emails were landing in spam and nobody could tell us why. They rebuilt the whole sending setup, which took about three weeks and felt slow at the time. Replies started coming back the month after.”
Questions about this problem
Do Google and Microsoft treat cold email differently?
Yes. Microsoft is stricter about catch-alls and sudden jumps in volume, so we track and cap Microsoft recipients separately.
What happens if a sending domain gets blocklisted?
We see it the same day, pause that domain and move its volume to reserve inboxes while it recovers, so campaigns keep running.
