Why are my emails not sending?

If your emails are not sending as expected, don’t worry—there are several common reasons that might be causing delays or errors. This article will walk you through a checklist to help you identify and resolve the issue.  

To see exactly why a specific email hasn't been sent, simply click on the unsent email in the Campaigns tab of the Email History page. At the bottom, you’ll find the reason listed.

1. Processing Queue

If you’ve just started your outreach, your emails might still be queued for sending. This process can take time, depending on the number of emails and whether they require verification. If there are errors preventing emails from queuing (e.g. out of email verification credits), they will be visible so you can take action accordingly. You can also monitor progress in the "Campaigns" tab on the Email History page.  

2. "Next Send" Time

To protect your sending reputation and increase deliverability, LeadSwift throttles emails based on your account settings. Check the "Next Send" time in your Email History to see when the next email is scheduled to go out.  

3. Last Email's Errors

Click on the “Last Email” in your Email History to see if there were any errors with the most recent message. For example, if there’s an SMTP Authentication issue, recheck your account settings to ensure your sender email is configured correctly.  

4. Sending Limits

In the "Accounts" tab, check whether your daily or hourly sending limits have already been reached. If so, additional emails will be paused until your limits reset. You can adjust these values in your account settings.  

Note: Any unsent emails/sequences from previous days because of sending limits roll over to the next day, counting towards the subsequent day's limits. If there are a lot of initiated emails with low sending limits, any new outreach campaigns will be delayed. The emails are sent in the order that they are queued.

5. Schedules

If you see a number under the "Scheduled Emails" column, it means your emails are waiting for the scheduled send time. Click the number to review or modify your schedule settings.  

6. Pending Emails

If none of the above apply, take a look at the queued emails in your campaign. Here's what different statuses mean:

  • Pending: Emails are being throttled based on your sending limits (e.g. max emails per day/hour).
  • Error: An issue has prevented the email from sending. Click to view the exact error message.
  • Sequence Waiting: The email is waiting for a follow-up trigger as configured in your sequence settings.
  • Over Schedule: The send window has expired. For example, if you scheduled 100 emails for a single day but only had sending capacity for 20, the remaining 80 will show this status once the date passes.  
 

By working through this checklist, you should be able to troubleshoot and resolve most email sending issues.
