Email Marketing with Dedicated IP

A: Emails need to be sent out from servers having public IP addresses. If exclusively your emails are being sent from an IP address, it is said to be a dedicated IP.

A: Email marketing providers or Email Service Providers(ESPs) assign one or many IP addresses for your emails to be sent from. These IPs internally can send your mails along with mails from other senders. In that case, this IP is a shared IP. In case yours are the only emails being sent from an IP, it is a dedicated IP address.

A: It is suggested to use dedicated IPs since you’d want your domain reputation and campaign performance not be affected by other senders in a shared IP. For example, if you are sending to corporate domains where IP address whitelisting is needed for regular email-sending, a dedicated IP is very useful.

A: If you have a steady mailing volume and are sending over 100k per week, it is suggested to use dedicated IPs to send emails. Sending too few emails can reset the IP reputation over time.

A: Yes. Since you are not sharing the IP with a bad sender this ensures that you are in complete control of your email deliverability. But, if you have an irregular email sending pattern, it is suggested to use a shared IP to avoid IP reputation reset.

A: The need for IPs is determined by your list size and your practices. Most providers recommend 1 dedicated IP for every 25,000 to 100,000 emails you plan to send to at the same time.
