If you own a business or if you are handling marketing for your employer, you know that you cannot send emails blindly. When you do this, it can lead to bounces. Bounces can destroy your sender’s reputation. Here, SMTP email verification can help.
SMTP or Simple Mail Transfer Protocol verification is the behind-the-scenes or quiet handshake that verifies the existence of email boxes. It can verify the email addresses without actually sending an email.
SMTP Email Verification – What is It?
SMTP email verification is the process of authenticating an email address by directly communicating with the mail server of the recipient. It will not send actual message. Rather, it will connect through the Simple Mail Transfer Protocol. Then, it will ping the server on the existence of a specific mailbox.
During this process, the domain is validated also the mailbox availability is ensured and catch-all addresses are caught. This step helps businesses maintain a clean set of databases. As it gets rid of invalid, fake and inactive email addresses before a campaign, SMTP email verification can safeguard your deliverability. Not only deliverability, it helps ensure that marketing budgets are not wasted in the form of bounces. Here is how SMTP Email Verification works:
1. The Basic Check
A couple of quick automated checks are carried out before the SMTP handshake happens. As a result, processing power is saved.
Primarily, the verification tool will carry out a syntax check to ensure that email addresses look right without any illegal characters.
It will then query the Domain Name System to see if the domain associated with the email address actually exists. Also, it will check whether the domain servers are configured to receive emails.
2. The Core SMTP Handshake
In this step, the SMTP email verification tool will connect to the mail server of the recipient and initiate a standard SMTP conversation using particular commands like HELO, MAIL FROM and RCPT to.
For this, the recipient server will respond with a status code. It will reply with a particular code if the email address is valid. In the same way, it will reply with a different code if the address is invalid. Before a single piece of actual mail body text is transmitted, the tool will terminate the connection.
3. The Catch-All Catch
The important limitation associated with SMTP verification is catch-all and accept-all domains. Yes, mail servers of some businesses are configured to signal okay to every single command, irrespective of whether the user exists. This is done to prevent scanners from spotting corporate email structures. It means that these email addresses need advanced behavioral algorithms to flag them as risky addresses.
