Email Service Driver

The ESD, or Email Service Driver, is a module that facilitates the integration of known and recommended Email Services for NexoPOS. Using the default mail function provided on regular PHP applications tends to be inefficient, and emails sent that way either do not arrive or land in the Spam folder.

With the ESP, you can configure services like Mailgun, SendGrid, PostMark, or any SMTP on NexoPOS. Some of these services offer a free tier, allowing you to send emails for free.

Supported Drivers

The main action will be to decide which driver you want to use on NexoPOS. Here is the list of the supported drivers :

• SMTP: here any provider with SMTP credentials is compatible
• Mailgun: it's free tier offers 100 emails per day.
• Postmark: Also offer free 100 emails per day.
• Resend: which has 3000 free emails monthly so around 300 emails per day.

For Mailgun, PostMark, and Resend, you'll need to create an account to receive their respective API keys and tokens. For security purposes, you must own the domain from which you want to send emails.
