Why would you need an email verification service?

You spent time and resources building your email list. It is one of your most important digital marketing assets. No doubt. Keeping it clean helps you:

email verification results Bouncer review
  1. Reduce spam complaints: for every 5,000 email messages sent out you should receive less than 5 spam complaints.
  2. Remove risky emails: “accept all”, role-based and disposable email address are considered risky. They get lower engagement and bounce more often.
  3. Eliminate hard bounces: emails that no longer exist and fictitious emails are the most common causes of hard bounces.
  4. Avoid blacklists: getting backlisted stops all your email delivery to certain servers.

An email validation service like Bouncer will help you with all the above to keep your list healthy.

Bouncer Review: Email Validation Service

All your email marketing effort is wasted if the emails aren’t delivered right to the inbox. The last thing then you want is for emails to bounce, or even worse, your campaigns ending up in the spam folder!

Bouncer is an email verification tool that makes sure your email list is deliverable. It gives you the tools to validate and verify email addresses and keep your sender reputation.

Let’s go through these features.

What is Bouncer and how does it validate emails?

Bouncer checks if email addresses are deliverable, without actually delivering emails to inboxes. This is done in multiple steps to check for hard bounces:

  1. Syntax check: looks for any invalid emails that contain special characters or spaces that would bounce.
  2. Domain check: makes sure that the email address exist at the host domain. And will tell you if the email is registered and working.
  3. Ping check: establishes a connection with the recipient’s SMTP server to determine its status.

Before you even use the tool. Bouncer can give you a close estimate of the quality of your file. So you can test the quality of your list, without actually verifying it. This is free of charge.

Bouncer uses an algorithm to sample a part of your file and report you back the quality. This is a unique feature that shows you how many emails may bounce back after you send your campaign.

To use the Email Checker, just upload or even drag and drop your email list into Bouncer.
