Hi,
When I create a form, I test it from a few email addresses. If it goes through do I have to worry about deliverability?
I don’t typically add SMPT plugins. What’s the norm?
i guess if it’s not broke you don’t need to fix it! but often there are issues so i do have to end up using smtp.
would be interested to hear what peninah says!
It depends on which hosting you use.
Did anyone have had a case that they stopped getting emails because of this?
Why should it be a problem?
I use Cloudways a lot and they need SMTP anyway 
I don’t know that you MUST set up SMTP, but I think it’s a good idea.
Thank you all!
To further clarify: is there a difference between an email going to the website owner and form user?
What about the form software used? Gravity Forms / Forminator?
A difference in what way?
If I tested the form to the admin - it should continue to work. As opposed to notification emails which go to diff email addresses each time.
