    We have been using this for a month now and we are seeing that some of the submissions are not getting emailed to us and the only way we know we got them is by logging in to our workspace. What could be causing this and how do I troubleshoot it to correct it?

    Hi Ingram,

    Thanks for using Jotform. I checked the email address and found it on our bounce list. Check out the reason below:

    Reason(s) : bounced (host mx1-us1.ppe-hosted.com[67.231.154.162] said: 550 5.7.1 : Recipient address rejected: User email address is marked as invalid. (in reply to RCPT TO command))

    I've removed it from our list. Whitelist Jotform's IP addresses and domains to your email, and add noreply@formresponse.comnoreply@jotform.comnoreply@jotmail.com to your contacts list.

    Also, setting up SMTP helps streamline the process of sending emails from your application or server. It ensures that emails are delivered securely and reliably to recipients. You can easily set up a custom SMTP to use your email sender as provider. Let me walk you through it:

    1. Go to the Settings page while logged in to your Jotform account and click on Add Sender Email in the Sender Emails section.

    2. In the window that opens, select Custom and click on the Continue button.

    3. Enter your email provider's details, click on Send Test Email to check if it’s set up correctly, and then click on Save.

    Perfect, that helps a lot.

    One question.

    First, since we currently have the free tier, any limitations on setting up an external SMTP relay?

    Hi ingramtract,

    As for SMTP go, all functionality is the same regardless of the plan you have. The starter plan doesn't have any SMTP limits that would increase if you have a paid plan.

    Reach out again if you have any other questions.
