This is analagous to what happens with most sendinging services. You are usin Most sending services use a large bank of IP addresses for all their customers. The  advantage of doing this is the low cost for the service and you the customer.

The down side is that these IPs routinely get flagged and blocked due to other users who abuse the system or send spam.

All 123Mailservices accounts are given their own unique set of IPs. This has the following advantages:

  • Better IP reputation management - Establish and be accountable for the reputation of your IPs. Your emails won't be sent on IPs that deliver emails from less reputable senders.
  • Troubleshooting deliverability -  With dedicated IPs, you can trouble shoot the possible causes of why your emails are not being delivered.
  • Standby IPs - In the event one of the IPs are blacklisted, we will swap in one of the standbys to maintain your deliverability.


To preserve the reputation of your IPs and increase the deliverability of your emails, we rotate the IPs in your pool every couple seconds:

  • Low send rate - Helps keep the effective send rate for an IP comparatively low.
  • Reputation management - One IP does not flood the receiving server with emails; reducing the chances of the IP getting flagged or blocked
  • Improved deliverability - Emails have a better chance of getting into the recipients inbox
