Email Domain Warm-Up
What warm-up is
Domain warm-up gradually increases how many emails a domain sends each day. Inbox providers like Gmail, Outlook and Yahoo are cautious with domains that suddenly send large volumes. Without warm-up, a new domain is more likely to see spam placement, throttling and blocks.
How automated warm-up works
When warm-up is on, FunnelStreams sets a daily sending limit for your dedicated domain and raises it step by step as your results stay healthy.
- New domains start with a small daily volume that grows over several weeks.
- Existing domains with sending history start higher, based on recent volume.
- If bounces or complaints rise, the schedule slows or pauses until things improve.
- Emails over the day's limit are queued and sent the next day.
Turn it on
- Go to Settings → Email Services → Dedicated Domain.
- Open your verified domain and turn on Warm-Up. The feature is in beta, so request access if you don't see the option.
- Review the daily limits and progress on the warm-up dashboard.
Get the best results
- Send to your most engaged contacts first.
- Keep your sending steady day to day.
- Connect Google Postmaster Tools so you can watch your Gmail reputation during warm-up.
- Avoid large one-off blasts until warm-up finishes.
