Chargify sets the “From” field in the e-mail to the address you specify in your site settings. However, because the e-mail comes from our servers, the chargify.com DKIM & SPF will be used. For the vast majority of our customers, this means the message is considered authentic and will not be blocked by spam filters.
In today’s day and age (i.e. the age of spam), mail deliverability is a critical issue. In order to assist you in getting your mail delivered, here are the current mail servers in use by Chargify:
One way to use this information to increase your chance for successful deliveries is to create an SPF record such as the following:
v=spf1 a mx include:mailer.chargify.com [other mechanisms you add to describe sending hosts] ~all
Note: as we strive stay on the edge of deliverability best practices, we may change our sending hosts from time to time. Please watch this page for changes.
Don’t forget, you can always check to see if your SPF record is public - using a tool like the SPF Query Tool.
