If an automation workflow doesn't send to subscribers as expected, there are a few things to look for. If this article doesn't point you in the right direction, contact our Support Team for a closer look.

Is the automation paused? Still in draft?

Automations that haven't been started show a draft icon next to their title that looks like this:

Automations that were running but have been stopped show a paused status icon that looks like this:

If either are present next to your automation workflow title, then it isn't currently sending and would explain why you subscribers didn't receive that autoresponder campaign. To start or resume a workflow, click its Edit button and navigate to the Confirm step. Click Start Workflow or Resume Workflow to start the automation.

Do the subscribers meet the workflow's trigger or segmenting conditions?

Take a look at your trigger settings on the Trigger step, and make sure they're what you expected them to be.

  1. Navigate to the Automation page.
  2. Click Edit next to the workflow you need to look into.
  3. Go to the Trigger step to see your settings.
  4. Check what's listed under Trigger workflow when the following conditions are met? heading.
  5. If you've added additional segmentation conditions, check those to see if they might have limited your subscriber base too much.


Subscribers often miss automated emails when the workflow is triggered by signup date. Be sure that you checked the box for Trigger workflow when subscribers are imported, to include all new subscribers in your workflow. Otherwise, we'll only send your automation workflow to subscribers who sign up on your MailChimp form.

When are your automated emails scheduled to go out?

If you've made changes in the Advanced delivery settings section of the Trigger step, you may find that subscribers don't receive emails at the times you expected, or in some cases, at all. Often, the default settings are the most effective way to make sure all your subscribers receive their emails when they're supposed to.

Using date-based workflows, like birthdays or special events, can be especially tricky. Since those emails have to go out on specific days, as they relate to the trigger date, if you limit what days of the week your emails can be delivered, you could skip subscribers whose next email should arrive on a day you've opted not to send.

This is also the case with limiting the time of day you send. If someone triggers your workflow during the sending period, but the next delayed email in the series would be sent outside of the sending period, it will queue up for the next available send time.
