FallBack to SMTP when SendGrid Fails/Exceeds Quota

[mrsaicharan1]

Describe the feature request
We need a feature in the system where the SMTP protocol must be used when SendGrid's quota exceeds/ fails to work.
This is essential as whenever someone orders a ticket, they expect the tickets/invoice to reach them via mail. A backup service like this would be useful.

Additional context
Working on it.

A simpler version should be implemented first. An email sender object that provides an interface like send_email so that we can just use it. And internally it checks the configuration and uses sendgrid or SMTP according to config present. Then it can be enhanced to add the fallback usage

[mrsaicharan1]

Oh, okay ! @iamareebjamal , just to clarify, we have two separate tasks written out, send_email_task for Sendgrid and send_mail_via_smtp_task for SMTP. Do you mean that we just need one method which checks for the internal config and sends it according to the enabled protocol?

Correct
