Boost Your Email Deliverability With Proper List Hygiene

If you send emails, verification tools should be part of your stack. Here‘s why:

  • 26% of email addresses go bad yearly – Invalid emails turn into non-stop bounces and errors.
  • 20% of signups can be fake or spam – Spambots constantly flood forms with garbage contacts.
  • Unverified emails see 2-3X lower open rates – Recipients ignore questionable senders as unsafe.

Luckily, solid email verification avoids these issues through processes like:

  • Confirming well-formed email structures
  • Checking domain and mail server validity
  • Detecting spam traps and catch-alls
  • Identifying role accounts and aliases

And with open rates directly driving metrics like CTRs and conversions, it pays to verify.

Now let‘s explore the top email verification services and how they stack up across different use cases.

When regularly blasting 500K+ emails, industrial-grade deliverability matters.

Tools like Bounceless and Copernica offer advanced traffic routing, dedicated IP allowances, and other optimizations so huge lists reach their audiences.

Optimizing Developer Workflows

If your dev team handles email collection/management in custom apps or platforms, choose solutions with solid coding capabilities.

Both Kickbox and MailboxLayer stand out for smooth SDKs, pre-made libraries, and self-service APIs simplifying integration.

Pro Tips for Making Email Verification Count

While core list processing drives most value, don‘t miss some pro tips for making your efforts stick:

  • Retest and update monthly – Set a calendar reminder to rerun checks capturing new bounces and spam traps.
  • Automate ongoing verification – Use rules and workflows to validate new signups in real-time.
  • Compare accuracy rates – Confirm tools have 95%+ accuracy before fully trusting them.
  • Isolate risky contacts – Move uncertain emails to separate groups for further testing.
  • Personalize risky outreach – When re-engaging risky subscribers, use customized messaging highlighting their original signups.

Little ongoing hygiene steps like these will dramatically boost your deliverability and campaign performance over time.

Now let‘s wrap up with some key takeaways.

In Closing

  • Prioritize accuracy and integrations fitting your existing infrastructure.
  • Align tools to any compliance, privacy or high volume considerations.
