Before massive email campaigns

Please have in mind these are field notes organized in a common structure that I use for myself or for my students, university classes and industrial activities. They may be messy, with errors and in some cases, without proper references. If you find your work (or part of it) here without proper acknowledgement, please let me know so I can fix it as soon as possible.

This is not an extensive list but just what I've learned from doing it. I'm not an expert, so it's very perfectible.

I think the first you need to do is test the health of your domain. For this I can recommend MxToolBox's Email Health Report

If you never used your domain for email campaigns, usually this report will throw some errors, mainly related to:

• SPF
• DKIM
• DMARC

What are those acronyms? here is a simple explanation: SPF and DKIM are email authentication methods. SPF set the server that can be send emails and is already configured in GoDaddy (it seems that Google did it automatically); DKIM helps prevent spammers and other malicious parties from impersonating a legitimate domain (we need to activate this); DMARC is a set of rules to instruct emails servers to report to us when something goes wrong at their sides.

Also is useful to be in the email delivery list (at least at the beginning), just to debug how emails are being received by our users. To do that you can use the Messageheader toolof the Google Admin Toolbox.
