When to use a dedicated IP address

A dedicated IP address in your SMTP2GO account means that all of your emails are sent out from an IP address that is only used by your own account. This means that the reputation of your IP address in the email community is solely determined by the emails that you send. Also, if you send a lot of emails to particular corporate domain names, a dedicated IP address can make whitelisting with them easier.

It is important to note that a dedicated IP is not suitable for everyone. You should be sending enough emails through your SMTP2GO account on a regular basis in order to maintain the reputation of your IP address. A minimum suggested volume is 5,000 emails per day, at least 3 days per week.

SMTP2GO accounts on plans that allow at least 100,000 emails/month are automatically assigned one dedicated IP address. Larger senders may wish to purchase additional dedicated IP addresses. Two reasons for wanting multiple dedicated IP address are:

  1. You are sending more than 500,000 emails per month. Some email providers (such as Outlook and Gmail) restrict the number of emails they accept from an individual IP address per hour or per day. Using more than one dedicated IP address often benefits large senders by getting around such restrictions.
  2. You are sending both transactional emails (such as welcome emails, or receipt of purchase emails), as well as marketing emails. If you have enough volume of each type, you can create an IP Pool for each type on the 'Settings > Dedicated IPs' page. Then, from the 'Settings > Users' page, assign a different SMTP user to each pool. Your important transactional emails can then be sent from a different IP address to your marketing emails.
