Do I need a dedicated IP address?

It depends on several factors but here is what we recommend.

Use a dedicated IP:

  • You are sending more than 50k email per week, in order to isolate your reputation.

Use a shared IP:

  • If you are sending less than 5,000 messages a day, a shared IP may be the right solution for you.
  • Your email sending is volatile with large spikes of volume, may assume those large spikes are spam.

Use a pool of dedicated IPs:

  • You are a high volume sender, limit the total volume per IP per hour.
  • To separate IPs for your bulk and transactional mail.
