Hello,

I have to use Smart-Content on our Double Option E-Mail when a Contact uses a special Form. To use Smart-Content the Contact has to be in a specified List or in a specified Life Cycle Phase.

My idea is, that the Form triggers a Form-Workflow and adds the Contact to a List. Then the System Double-Optin E-Mail is send with the Smart-Content, because the Contact is in the list.

I tried it on a developer System. And it looks like that it works. But can someone confirm the System Process Order for me, or is it just luck? I cant build on luck 🙄  
Thanks for an answer 😃

Hi @MalteHoffmann,

It is luck – or more specifically a portal that is still fast enough to process the active list used for the smart rule.

As portals grow, list processing speed slows down which means that workflows are usually faster at sending emails than lists are at populating. This means that an email might be sent before a contact enters the list needed for smart content.

This can usually be avoided by a short delay in your workflow (for example 1 minute), giving the smart list time.

Personally, I’m not a fan of smart content in double opt-in emails because of that reason, as the 1 minute delay lowers the likelihood of a confirmation. Instead, I’d recommend reconsidering how important that smart content is and whether its expected benefits outweigh a lower confirmation rate.

If the information used for the smart rule is being made available through the form, I’d recommend workflow branches with separate emails instead of smart rules, as form input information is available immediately.

Best regards!
