Prepare sending mailboxes before starting a cold-email campaign.
Cold-email warmup is a gradual sending activity intended to prepare a mailbox before campaign use. It does not guarantee inbox placement or protect a domain from poor list quality, unwanted messages, or sudden volume changes.
Plan the warmup process
- Start with sending setup: Check mailbox authentication and sending limits before warmup.
- Increase activity gradually: Avoid sudden changes in volume and monitor mailbox health.
- Review before campaigns: Confirm the audience, consent or other contact basis, suppression lists, and sending rules before outreach.
Keep deliverability expectations realistic
Warmup alone does not establish sender reputation or ensure delivery. Follow mailbox-provider rules, monitor actual sending results, and stop if complaints or delivery problems rise.
Best fit for
- Teams preparing new mailboxes for permitted business outreach
- Operators coordinating mailbox setup and campaign review
- Agencies documenting sending practices for client approval
Cold Emails Warmup supports mailbox preparation; it does not replace permission, list-quality, or sending-limit checks.
