Hi @AryanPrakash!

This error occurs because the SMTP Server is incorrect. So instead of “smtp@gmail.com” please type smtp.gmail.com.


Thanks Alot @ovi.
That was a silly mistake :slight_smile:

Hi @ovi
I have configured everything in SMTP yet i get an error message saying - "The specified string is not in the form required for an e-mail address. "

Can you send the screenshot of the activity and properties and error message.
And also Check givien mail id is correct or not.

Hi @arivu96
The given email id is correct and i am attaching the screenshot.Please check.

This is the error i get-


Remove the properties->sender->from and name
And try again

Arivu :slight_smile:


Thanx @arivu96 . It worked :slight_smile:

Facing an issue with SMTP as in attached screenshot.

This was resolved, i had configured wrong SMTP port. Now i am facing issue like invalid credentials even though my credentials are correct.image

it is still throwing error statement even after doing what you stated . From properties section i removed from and name .
any other solution to this issue to resolve ?

Hi Arivu, could you explain why we need to remove sender? Cause I always use that and this time it doesn’t work. Thank u
