Maintaining IP Address Reputation
Your static IP address earns a reputation as it sends emails.
By following good sending practices you can
maintain a good reputation, and increase the likelihood that your emails
will be delivered to recipient's inboxes instead of being placed in
spam.
Feedback Loop Reports (FBLs)
When a recipient marks your email as spam, this hurts the reputation of
your IP address. To help keep a good reputation, promptly remove
anyone who requests to be removed/unsubscribed. You can also sign
up for Feedback Loop Reports (FBLs) from many of the major email
providers (AOL, Comcast, Hotmail, etc). This will provide you with
valuable information on how many and which users marked your emails as
spam, so you can remove these users from your mailing list.
SPAM Blacklists
There are many spam blacklists maintained that keep track of IP
addresses known to send spam. Receiving mail servers may subscribe
to these blacklists, and not accept email from you if your IP address is
in a blacklist. You want to make sure your static IP address is
not in any of these blacklists. You can check if your IP address
is in any of these blacklists with a variety of online tools. Just
search for spam blacklist check to find a list of these tools. If
your IP address is in a blacklist you can request it be removed, but you
need to make sure you are following good sending practices to make sure
it stays out of these blacklists.
