Hope this article is useful to our readers. We discuss a few things you must do to ensure before sending emails to someone.
These are common mistakes from many. Even for the service providers, it is common to find these mistakes for those incoming emails.
I’m listing them here and you can check if you have done these or you should you quickly rectify them.
a. Find out your SMTP Mail server IP address, It is important to know which IP address your emails are sending out from.
b. Once you know the outbound IP address. Go to MXtoolbox https://mxtoolbox.com/blacklists.aspx to check if your outbound IP address is blacklisted by the popular RBLs.
Make sure your IP address is not blacklisted, otherwise your emails might be rejected at your recipients’ mail server.
c. Now, we make sure this outbound is listed in the DNS SPF record using this tool https://mxtoolbox.com/spf.aspx.
d. PTR record or rDNS on your outbound IP address. Using this https://mxtoolbox.com/ReverseLookup.aspx
e. You can enhance your email delivery by adding DKIM. DKIM is a kind of signature acts as the emails are sent by the sender via the permitted mail server. Most tools online are not friendly for the layman. Just write to our support team with the email address you want to check, our engineers will find out for you.
f. DMARC – This is yet widely practised and this will not work if your recipient’s mail server does not do a DMARC check. DMARC prevents spoofing and phishing like you have SPF, DKIM or both. DMARC does a bit more, like sending reports and action published in the DMARC record.
We encourage domain to publish DMARC and the above to protect your business and brand.
