We recently shared some instructions to modify our Email Marketing software to support sending mailings using Amazon SES (Simple Email Service).

With Amazon SES there is no long-term commitment, minimum spend or negotiation required – businesses can utilize a free usage tier and after that enjoy low fees for the number of emails sent plus data transfer fees.

This modification came from an Email Marketing user, who successfully configured his downloaded install to send using SES, instead of the default sending method. We created a forum post detailing how this can be done.
The modification simply overrides PHP’s mail() function with SES. Within the Email Marketing software, make sure your mail connection is using the “Default Sending Method”:

Please note: This is not an official ActiveCampaign feature. This modification requires editing core software files. We cannot support any problems or loss of functionality you experience after attempting these changes. Please exercise caution when modifying software files, and backup files before making changes. Please limit any problems, questions, or improvements to the forum post, and not official ActiveCampaign support.
Please review the forum post for requirements and specific instructions. Have your Amazon Web Services access ID and secret key ready.
