Why doing an email warmup is essential
A domain or IP with no history might look suspicious to mailbox providers. IP or domain warmup means gradually sending emails over time to gain trust. This phase helps you:
- Avoid blocks and spam folder issues
- Warm up your email address in the eyes of ISPs
- Monitor performance and fix potential issues
- Establish a strong, lasting email sender reputation
Key steps for a successful warmup strategy
- Start with an engaged list: send to your most active contacts first
- Segment your list to adjust volume based on response
- Create a warmup email plan over several weeks
- Track open rates, clicks, bounces, and spam complaints
- Adjust your emailing ramp-up based on results
Best practices to avoid blocks and build your reputation
- Use simple and tested content to start
- Avoid attachments, suspicious links, or heavy visuals
- Authenticate your domain with SPF, DKIM, and DMARC
- Keep a consistent sending schedule
- Never force sends to inactive addresses
