Sends from your Gmail
Messages go out through your own connected Gmail account. Your address is the sender, your Sent folder holds every copy, and replies land in your own inbox. We run no sending servers of our own.
Private invite-only beta
Cold email from your own mailbox that keeps landing in inboxes.
ColdMerge sends your outreach through your own Gmail or Google Workspace account. It paces and ramps your sending to protect your domain's reputation, and it watches for replies and bounces so your follow-ups stop the moment someone answers.
What it does
Paces to protect your domain
New mailboxes ramp up gradually, sends are paced with randomized gaps inside a working-hours window, and real unsubscribe and suppression handling is built in. No fake warm-up traffic.
Detects replies and bounces
Follow-up steps run until a real person replies, then stop automatically for that conversation. Permanent bounces suppress the address so you never email a dead mailbox again.
Who it is for
ColdMerge is built for solo founders and small sales teams sending genuine one-to-one cold outreach from their own mailbox. It suits people who care more about protecting their sending reputation and staying compliant than about blasting the highest possible volume.
Currently invite-only
ColdMerge is in a private beta while we work toward Google's full verification. There is no public signup yet, and you cannot buy your way in. Access is by single-use invite code only.
If you already have an invite code, sign in at app.coldmerge.com. If you would like a code, or have any question about the product, email us and we will get back to you.
