Email Validation
What is email validation and why is it important?
Email validation is the process of detecting whether or not an email address is active and valid.
Email validation is almost crucial in email marketing.
Email validation is a quick process that detects typos.
Email validation also verifies whether a specific email address is linked to a reputable domain.
Email validation checks email addresses at the point of entry into your database.
Email validation also protects your email sender score, allowing you to get the most out of your email software.
Email validation is simply checking for an @ symbol in your email field, or for a full stop and a standardized suffix.
An email address linked to a valid is not enough if it’s only the syntax.
This is why email validation is important in email marketing.
Email validation shields you from email hard bounces that could ruin your sender’s reputation and blacklist you.
Top 5 mistakes you’re making with email validation
Mistake 1 – Making people enter their address twice
You think to stop invalid emails from sneaking into your email lists is through email confirmation or a double-entry field, you’re making a major one of the email marketing mistakes.
But typing is troublesome since typo mistakes can happen.
Adding an additional field for email confirmation means an increased risk of errors and a potential reduction in completion rates.
There is a huge chance your users are going to try to copy and paste the email address from the first line.
If the email is written incorrectly at first, you are just as likely to enter it incorrectly twice.
This is especially the worse for mobile users.
This is one off the common email marketing mistakes.
Email validation is a no-brainer for detecting invalid email addresses.
But you wouldn’t if the entered email address belonging to the person who signed up.
To check that, you need to send a confirmation email with a unique link.
This is the double opt-in confirmation method.
The double opt-in is the only real way to confirm that the person signing up for your list actually wants to hear from you.
Double opt-in is more practical and way better than asking the recipients to type the email twice.
The numbers show that the double opt-in lists get up to double the clicks and double the opens of single opt-in lists.
Double opt-in gets you half the hard bounces and half the unsubscribes of single opt-in so it’s a win all round.
Mistake 2 – Not using inline validation
Inline verification is a great way of avoiding user confusion by correcting field errors along the way.
This way you avoid angry red error messages about fields you’ve filled in incorrectly.
Mistake 3 -Not providing clear labels
You need to provide clear labels about how and why you need your users’ email addresses.
Clear labels will encourage your users to stay subscribed to you.
If you provide this information to your users, you can prevent them from abandoning your form.
Like this, you will avoid one of the many common email marketing mistakes.
Mistake 4 – Regex validation
This is one of the common email marketing mistakes is the way to use a regular expression (or regex) to validate email addresses.
Regex is easy to implement, but it can be too restrictive.
A regex to validate email addresses can be more complicated than you first think once you’ve read the RFC.
The RFC is a 47-page technical spec describing what a valid email address is.
The RFC is applicable to SMTP (Simple Message Transfer Protocol) and email addresses.
The REC is something that most people presume will be easy, until you drill into it and figure out just how complicated it can be.
Mistake 5 – Being too restrictive
If you’re too strict with your validation, it could cost you some subscribers, users, and maybe customers.
Check if the email addresses have the common characters often used in email addresses such as a slash (/), equal sign (=), or exclamation (!).
slash (/), equal sign (=) or exclamation (!) are all valid symbols, so if your software is rejecting these you are literally turning potential leads away.
This is a very common email marketing mistake.
