Boost Campaign Success with Verified Emails

Smartlead’s email verification tool checks the validity of each email address in your list by performing several checks: syntax validation, domain DNS lookup, SMTP server verification, and detection of temporary or disposable emails. It also checks for catch-all domains and ensures emails aren’t listed on blacklists. Once the verification process is complete, Smartlead provides a report showing which emails are valid, invalid, or risky, allowing you to optimize your outreach.

Verifying emails ensures you're sending messages to real, active addresses, which improves inbox placement. Invalid emails and low-quality addresses can damage your sender reputation, leading to higher bounce rates and spam filtering. By cleaning your email list and removing these addresses, you increase the chances that your emails land in the inbox, not the spam folder. This leads to higher engagement rates, more opens, and better overall deliverability.

If you don’t verify your email list, you risk sending messages to invalid, non-existent, or low-quality addresses. This can result in high bounce rates, a damaged sender reputation, and emails being flagged as spam. It also wastes resources by targeting unengaged recipients. Verifying your list ensures you're only emailing active, deliverable addresses, improving your email performance and safeguarding your reputation with email service providers.

To verify your email list with Smartlead, simply create a new campaign, upload a CSV file of your leads, and map the relevant fields. Then, click “Launch Verification & Proceed.” Smartlead will process the list, checking each email for validity. Once the verification is complete, you can review the results in a report and download a clean, verified list. You can then use the verified list for campaigns to ensure better deliverability.

Email verification is not a one-time process. You should verify your email list regularly to maintain high deliverability and ensure your contacts remain valid. As your database grows or changes over time, emails may become invalid due to inactive accounts, changes in email addresses, or new spam traps. Re-running email verification ensures your campaigns always target valid and engaged recipients, preventing bounces and keeping your sender reputation intact.

Yes, you can verify individual emails with Smartlead. Simply enter the email address into the verification tool, and Smartlead will perform a quick check to determine its validity. The tool will show whether the email is valid, invalid, or risky, allowing you to make immediate decisions on whether to include it in your campaign. This is especially useful when you need to verify a small number of addresses quickly.

The time it takes to verify your email list depends on the size of the file being processed. For smaller lists, verification can be completed within minutes. Larger lists may take a bit longer. However, during the verification process, you can continue working on other parts of your campaign, as Smartlead will notify you once the verification is complete. The tool is designed to handle large volumes efficiently without delaying your workflow.

When an email is flagged as "risky," it means that while the email address might be deliverable, there are potential issues that could affect its performance. For example, it could be associated with a domain known for frequent spam complaints, or it could be listed on blacklists. Risky emails might still work but can negatively impact your deliverability and sender reputation. It's best to handle these emails with caution or further investigate them.
