Auto replies form JotForm being marked as suspicious

When a customer fills out a JotForm, they receive an auto reply that we set up. Well, come to find out, email accounts like google are marking JotForm auto replies as fraud and suspicious? Why??

See screen print below.

As I check the form, I see that you are using your own email address to send the auto-responders. Looking at the screenshot provided, it looks like that the sender email is configured using normal verification method. Instead, you may try setting up your email address using SMTP configuration so that it should be sending your email server. 

Please refer to the guide below that can help you with setting up SMTP for your form.

Hello. We are using paid Google Suites for emails. Do you have a link you can send me that will walk me step by step on how to configure our SMTP for G Suite (gmail accounts)?

Also, should I use our own SMTP email servers for all emails, auto res-ponders, and jotforms?

I have no idea what our port number is???

You may refer to the guide below that can help you with setting up SMTP account using your Google suite account. 

I have no idea what our port number is???

Since you are using Google suite, the port numbers are the same as Gmail and the above instructions in the above link should help with all settings.

Also, should I use our own SMTP email servers for all emails, auto responders, and jotforms?

If you want to send the emails using your own email address, you may configure the sender email with the SMTP email account. Otherwise, you may consider using the JotForm default email address as well.

Hope this information helps!

Hi. Can you confirm that we set up SMTP for our auto responder for our "Shopping Cart" JotForm?

We really need to make sure we do this properly.

I reviewed your form email settings and I confirm that the Advanced / Sender Email is now properly configured to use your own SMTP emails.

Let us know if you need further assistance.

Hi. We have most of our forms working but not all.

When a customer fills out the "Expert Resume Pros: Customer Feedback Form" we do not receive any email notifications. Same for every form titled "Expert Resume Pros".

Did we not set up the SMTP for these forms correctly???

Please help ASAP!!!

I have just checked your form and I did not receive the email auto-responder, but may be that the issue has to do with the SMTP settings, I would recommend you to contact your service email provider in order to make sure you do not have any limitation and you're using the correct credentials. 

Just to make sure the SMTP sender works, I have tested using my Gmail address as sender, using Gmail SMTP settings and it worked for me. 

Alternatively, you may use the Mandrill workaround: https://www.jotform.com/help/240-Set-The-Sender-Email-Address-With-Mandrill-Account

I hope this helps.
