How can I prep my IP address for better deliverability?
Whenever you’re sending outbound emails, you want to consider your domain’s reputation from the perspective of ISPs (Internet Service Providers).
This is especially true for newer IP addresses because if an ISP notices a sudden increase in email coming from a new IP address, they’ll most likely start monitoring its traffic.
Volume is one of the biggest factors ISP SPAM filters look at, so you’ll want to start sending low to moderate volumes. This will give ISPs the chance to observe your sending habits over time.
There are a few tools such as SenderScore.org & SenderBase.org that you can use to check the reputation of any IP.
