For separate IPs for transactional email, you generally want to use a dedicated IP address (or a small pool of dedicated IPs) from your email delivery provider.
What to use
- Dedicated IP for transactional mail if you send enough volume to keep it “warmed up”
- Shared IP if your transactional volume is low and you don’t want to manage warming/reputation
Best practice for transactional email
Use a dedicated IP dedicated only to transactional messages, such as:
- password resets
- receipts/invoices
- account alerts
- verification emails
Important notes
- If you use a dedicated IP, you’ll need to warm it up gradually
- Keep transactional and marketing mail completely separated
- Make sure you also have:
- SPF
- DKIM
- DMARC
- Monitor reputation and bounces closely
Rule of thumb
- Low volume: shared IP
- Consistent moderate/high volume: dedicated IP
- Very high volume: dedicated IP pool with careful segmentation
If you tell me your approximate daily volume and provider (e.g. SendGrid, Mailgun, SES, Postmark), I can recommend the best setup.
