The omnipresence of emails spreads far beyond that of any social media platform. After all, a person might not use any social media platform, but if they use the internet, they must have an email address. This is why email marketing still remains one of the best ways to generate leads for your business online.

However, emails come with one major drawback– you cannot verify an email address’s authenticity without sending an email. This is a real problem because you don’t want your emails to bounce back due to an undeliverable email address.

If you want to deal with this problem, you have already taken the first step by coming here; leave it to us now. We will guide you through the best ways to verify an email without sending it. It’s going to be an interesting blog, so make sure to read it till the end.

How to Verify Email Address Without Sending Email

1. Start With Checking the Syntax

Email addresses have a well-defined format, and it’s important for you to be able to identify email addresses that just don’t look right. If you have just a few email addresses to verify, your first step should be to check if it looks like a valid address. Here are the things to look out for:

  • Every email address consists of three parts: 
  • a username that comes before the ‘@’ sign; 
  • the ‘@’ sign; 
  • the domain name (such as,,, and so on)

If an email address lacks any of these parts, remove the address right away.

  • An email username can contain letters, numbers, and special characters such as underscore (_), plus (+), period (.), etc. However, Gmail usernames cannot contain an ampersand (&), equals sign (=), underscore (_), dash (-), comma (,), plus (+), or brackets (<>).
  • An email address cannot start or end with a period.
  • Periods cannot appear consecutively more than once anywhere in an email address.

If you want to verify only a handful of email addresses, this method might prove to be useful for a start. Of course, just checking the syntax isn’t enough– you still need to verify the address. To verify bulk email addresses, you need to take the help of Email Verification Tools.
