Why submissions are not coming through from SMTP email?Asked by smpteny on November 07, 2016 at 02:21 PM
Dear Jotform Support,
I got the following error message today, after my form emails were working perfectly before.
Note that I was on the train this morning testing my form, and received an error from Gmail (blocked sign-in attempt), probably due to cell data reception issue. I authorized my Gmail account (firstname.lastname@example.org) to accept a "less secure app", which it said was all set.
Also, I checked my Jotform SMTP settings-- still all OK, with no changes, and even deleted that email from my account settings, and then re-entered the same email and settings. All no help.
My form works fine using "noreply@jotform" as the return address, but I would really rather have it come from me.
Please let me know what you think.
Here's the Jotform Email:

All the best,

I did some investigation since we had recently some problems with Gmail addresses. The problem is that emails from Gmail (that come from JotForm) and emails from JotForm alone, all go to Spam folder.
So my first advice would be to check your Spam folder and see if any email went there. Also this is my configuration for SMTP (That worked):
And here are emails that I received (to Spam folder):
If you received as well, please mark them as 'Not Spam' like in my example above.
Please let us know how that worked for you.
We'll wait for your response.
Thanks for the reply. I'm still having the same trouble, even after making the settings the same as yours.
I checked my other Jotform account (oratoriosocietyofny), and noticed that in Account Settings, the emails are not-editable. You can delete them, but not edit. But, in my smpteny account, the email is editable. Could that be a clue?
If you are using Google SMTP Server to send emails, please make sure that you have followed the steps on this guide https://www.jotform.com/help/392-How-to-Use-Your-Gmail-Account-as-Your-Email-Sender-via-SMTP. You will need to turn off something in your Google account to allow the 3rd party apps to use your SMTP without restrictions.
When you also receive access verification from Google, make sure to allow it so Google will continue to send emails using the provided SMTP credentials.
With regards to the non-editable emails listed in your account, those are custom verified emails not SMTP emails. SMTP emails are editable, verified emails are not.
Hope this helps!
