Email Warmup

Email warmup builds your sending reputation so your cold emails reach the inbox instead of spam.

A brand new inbox or sending domain has no sending history, so mailbox providers like Gmail and Outlook treat it with suspicion and tend to filter its emails. Warmup fixes that by gradually building a healthy, natural sending pattern before you start real outreach, until providers trust the account.

With Sendr, warmup runs automatically on your inboxes. Sendr ramps your sending volume up gradually, generates the engagement that providers look for, and keeps warmup running quietly in the background alongside your live campaigns, so your reputation stays protected as you scale.

What it does for you

• Gets more of your emails into the inbox rather than spam.

• Protects your sender reputation automatically, with no schedule to manage.

• Keeps your deliverability healthy as your sending volume grows.
