Troubleshooting Emails

Last reviewed June 30, 2026

This guide covers frequently asked questions and common troubleshooting steps for issues that may arise when creating or sending emails.

Troubleshooting: emails landing in spam

Option 1

Update your domain’s DMARC policy to p=none. This prevents emails from being quarantined when DMARC checks fail.

Option 2

Use one of ShortStack’s default From Addresses:

no-reply@campgn.page
no-reply@lndg.page
no-reply@shortstack.page

Troubleshooting: recipient(s) not receiving emails

Possible cause 1

The Double Opt-In setting may be enabled if scheduled or follow-up emails aren’t being delivered. Here’s how to check:

Open the Email Builder.
Click the Company Profile link at the top of the Builder.
In the Company Profile settings, scroll down to locate the "Require Double Opt-In" option.
If it’s enabled, uncheck the box to disable it.
Click Save, then Select to confirm your changes.
Make sure your email is set to Active, then close the Email Builder.

Disabling Double Opt-In should allow your emails to send as expected. If you are required to have Double Opt-In enabled, include the merge code {{subscribe}} in your Autoresponder email.

Possible cause 2

The recipient unsubscribed from receiving emails. If you have multiple Company Profiles, it will only affect the Company Profile from which they unsubscribed.
