Why do I need to validate email addresses?

Lower email bounce ratesThe percentage of emails that are undelivered vs. delivered to the intended recipient.

Every invalid and fake email address on your list adds to your bounce rate.

Validate email addresses on your list every quarter to get rid of outdated contacts and keep your campaigns performing.

Improved email conversions

It’s simple - when fewer emails bounce, more people see your business messaging. With more eyes on your content, you can make more sales.

Validate email addresses on your list, and give yourself the best chance to reach your audience.

Better email deliverabilityA sender’s ability to reach the recipient’s inbox with their outgoing emails. It may also describe the ratio of emails delivered to the inbox vs. those sent to spam or blocked by the receiving server.

A dirty email list leads to poor performance (bounces, spam complaints, and unfavorable open rates), which will affect email deliverability.

Validate your email addresses and make sure your inbox visibility remains strong.

Accurate campaign analytics

You can’t build effective campaigns based on how they perform against fake or inactive subscribers.

Ensure your email list is up to date with real contacts, and get a realistic understanding of how your email marketing performs.
