Common best practice in email marketing is to segment your audience based on engagement and filter our emails with very low engagement to reduce the risk of getting flagged as spam or even hitting spam traps by recycled email addresses.
Let's first distinguish between the different types of emails that reach us today:
Look at the first type of emails send by SaaS services. You offer free accounts and have a high number of possible emails in your system.
You want to prevent users from signing up with disposable emails or putting spam trap emails in your signup form that will blacklist your sender IP. This can have an impact on other users of your system too since your transactional emails might be blocked by their email system.
Verify new emails during signup using an email validation service using an API or plugin. Read more about how to use CampaignKit's API to integrate email validation into your existing system.
You send informational emails like product updates to your user base. Companies are likely using catch-all email addresses with low engagement. Some of the accounts might be created with disposable email addresses which could cause high bounces. To protect your sender reputation, qualify your target email list by removing such email addresses before hitting send.
Another use case is verifying your curated list for cold outreach. Before starting to contact your curated list, make sure to verify the email addresses. Again it's all about protecting your sender reputation and cold outreach is a good candidate to cause damage to it. People are more likely to mark you as spam. One piece of advice: Never buy an email list on the internet.
Email verifier apply a couple of tests to an email address without sending an actual email:
With email verification services you can instantly remove invalid and low-quality email addresses from your email lists.
The example above shows the results of CampaignKit's free single email verifier. In this case, the email verifier verifies that the email address is valid and emails will be delivered. It also detects the catch-all characteristic of the email address. The email address gets a lower scoring.
