Email Validation Rules Explained

Although the Advanced Email Verifier has a very good email validation success rate, it is simply not possible to guarantee a 100% accuracy level due to certain factors that are beyond our control. The level of accuracy you can obtain depend on the inbound SMTP connection policy of the remote ISP or ESP, reputation of the incoming connecting IPs and many other factors.

To save your time and protect your IP address from being blocked, we added rules for certain email addresses and domains that force the program to automatically mark the email addresses as "Bad" or "Unknown" without even trying to validate them.

In this article we give the detailed explanation of why certain email addresses/domains are excluded by the rules and what to do if you still want to validate them.

Best Practice of Using the G-Lock Email Verifier

Understanding our Email List Hygiene, Verification & Validation Process

Our Email Validation Software like any other email checker tool can determine about 70-90% of bad email addresses. Advanced Email Verifier connects to the email addresses mail server, as part of the validation process, and asks if the user exists but NEVER send an email to the recipient. If the recipient’s server gives the response that the user exists, the Advanced Email Verifier marks the email address as good. If the mail server says that there is no such user, AEV marks the email address as bad. This means that the Advanced Email Verifier classifies the email address depending on the response of the recipient’s mail server.

The Best Formula for Writing Subject Lines

The main factors affecting email open rate are the sender, Subject, frequency, sending date/time and the nature of the message. Personal messages get a higher attention, followed by timely news. At the other side are pure email marketing newsletters and offers that look too good to be true. As your email will be competing with dozens of other marketing emails in the reader's Inbox, check out the tips below for good ideas how to write the Subject line.

Best Practice of Bounced Email Handling

A bounced email is an electronic message returned to the sender because it was not delivered to the recipient for some reason. To understand possible reasons of email bouncing, let's go deeper into theory and trace the path the message takes from the sender's computer to the recipient's Inbox.

To reach the target recipient, the email message must successfully pass through numerous phases. Your email newsletter software sends the emails to your SMTP server or to your ISP SMTP server (it depends on the SMTP server you use). The SMTP server gathers the emails and puts them in a queue, then it sends the messages to the SMTP servers of your recipients' Internet Service Providers by establishing a conversation with the SMTP servers, i.e by connecting to the port 25 on the recipient's SMTP server. The recipient's SMTP server tells the sender's server if it is ready to receive the message or not. If it is not, the sender's mail server terminates the connection and will try again later.

Using G-Lock Email Analytics to Track Email Campaigns

Good email senders understand the importance of a regular and accurate email campaign tracking and analysis. Using email analytics you can measure your email campaign performance over time, control its effectiveness and plan your future campaigns focusing on the recipients' interests.
