Can I use 'Trigger Email ' extension of Firebase without a "from" email address?

Question

I have a domain, but I don't have Email address yet.

I want to use 'Trigger Email' of Firebase for my domain only, is that possible? There is an item called 'Default FROM address' in the setting of 'Trigger Email', I think that an email address is necessary.

Does anyone know how to set up 'Trigger Email' without an email address?

Answer 1

You need to setup an SMTP service provider which sends the emails on your behalf.

Firebase lets you set a 'Default FROM address but the SMTP provider may filter out emails that do not meet their quality criteria.

Usually / Often one has to confirm with the SMTP provider that one is the owner of the "From address", sometimes the domain is enough.

This is a measurement against spammers using their services.

So it is more a question of what your SMTP provider accepts.
