Email Validation & Deliverability
Email validation is the process of verifying the accuracy and deliverability of an email address. It ensures that email lists contain valid, active, and safe addresses, reducing bounce rates and improving marketing effectiveness.
2.1 Email Validation Overview
What is Email Validation, and Why is it Important?
Email validation is the process of verifying the accuracy and deliverability of an email address. It ensures that email lists contain valid, active, and safe addresses, reducing bounce rates and improving marketing effectiveness.
How No2Bounce Detects Invalid, Disposable, and Role-Based Emails
· Invalid Emails: Checked against syntax errors, non-existent domains, and inactive mail servers.
· Disposable Emails: Identifies temporary email addresses created for one-time use.
· Role-Based Emails: Filters addresses like admin@ or sales@, which are often shared among multiple users.
Difference Between Hard Bounces and Soft Bounces
· Hard Bounce: Permanent delivery failure due to an invalid or non-existent email address.
· Soft Bounce: Temporary delivery failure due to a full inbox, server issues, or other temporary reasons.
2.2 Handling Different Email Types
What are Catch-All Emails, and Should You Send to Them?
Catch-all email domains accept all incoming emails, even if the address is incorrect. While some may be valid, many can lead to bounces or go unread. Sending to catch-all emails requires caution.
What are Spam Traps, and How to Avoid Them?
Spam traps are email addresses designed to catch spammers. Sending emails to these addresses can damage sender reputation and lead to blacklisting. No2Bounce detects and removes known spam traps from your list.
Role-Based Emails: Why They Can Hurt Deliverability
Role-based emails (e.g., info@, support@) are not linked to individuals and often have lower engagement rates. Sending marketing emails to these addresses can increase spam complaints and reduce deliverability.
Why Are Some Emails Marked as "Unknown"?
If No2Bounce cannot determine the validity of an email due to server restrictions, it is marked as "unknown." These addresses should be used with caution as their status remains uncertain.

How to Warm Up a New Email Domain
When using a new domain for email campaigns, gradually increase the number of emails sent to build a good reputation with email providers:
1. Start with a small number of emails to engaged recipients.
2. Gradually increase the volume while monitoring engagement rates.
3. Avoid sudden spikes in email volume to prevent being flagged as spam.
4. Use authentication methods like SPF, DKIM, and DMARC to improve deliverability.
By following these best practices, you can maximize the effectiveness of your email campaigns and ensure high deliverability rates.
