Hello Friends.. Today in this post we are going to learn How to Warm Up your Smtp server before sending the Bulk Email Campaign. Warming Up your server is very easy, for that you will have to just create a simple email draft without any image, link and exclude the special character.

Before create and send any email campaign you will have to check with some below points

Domain Name

Before Buying any Domain Check it on MXTOOLBOX. Domain should not be listed in any category as per below screen



IP Address

Before Buying and updating DNS you must have to check the IP Reputation and black listed record on MXTOOLBOX, if it is clear then you can proceed for waring up the server. If IP become blacklisted, chances will increase of IP to black list in SPAMHAUS ZEN category hence IP reputation will become very low and your IP can be black listed for a long period of time

As you can see in above image, this IP address is blacklisted in two categories UCEPROTECL2 and UCEPROTECTL3. My advise is to check IP address blacklisting status on MXTOOLBOX before creating any email server.


Reverse DNS Record

Point your IP address to your domain name and check it after 24 to 48 hours on MXTOOLBOX. I already have create post on this, you can visit below post for DNS and PTR record.
