Transactional Email - Email not allowed to be sent to recipient in a sandbox/developer test portal

DRead — Thu, 02 Mar 2023 20:59:46 GMT

Sending transactional emails in standard sandbox.

Error: Email not allowed to be sent to the specified recipient in a sandbox or developer test portal

It appears it has to do with `+xyz` in the email e.g. `user+xyz@email.com`

I can't find any settings that might fix this.

Hi @DRead,

As per this article, email recipients must be users in the portal: https://knowledge.hubspot.com/account/set-up-a-hubspot-standard-sandbox-account

"You can send one-to-one test emails and marketing emails from a standard sandbox account to existing sandbox users. If you send emails to contacts that are not sandbox users, the emails will not send because they are not users in the standard sandbox account. You can add HubSpot users within your sandbox account. Emails sent from a standard sandbox account will come from a different transactional IP address than the main account uses."

Best regards!

Hi @MRadovitzkyCo,

Thanks for reaching out!

To send a contact a transactional email from a sandbox or developer account, the email associated with the contact will also need to be associated with a user in the same developer account or sandbox as @karstenkoehler mentioned in his reply.

I'd recommend referring to his reply to see if this helps resolve your issue 🙂 If you're still running into this issue after trying out the suggested steps, can you please let us know?

Thanks,

Kristen
