Though doing bulk uploads of email is a great way to validate your email list, there is a more efficient way, Java Script email validation.
Java Script can prompt the user to correct the mistake before they enter your marketing funnel.
Once you’ve implemented the Java Script on your site, real-time email validation will be active.
If the email address that was entered is invalid, an error message will appear.
This way you know that you are sending an email to a real, verified email address. Our Java Script email validation is easy to add verification to your web forms in a matter of minutes.
The code seems to work, but I'm interested in hearing how it could be improved.
I'll include the code below, but you can run/fork it on Codepen.
Visit Stack Exchange I'm trying to improve my Java Script (I'm usually a copy/paste guy but can do basic DOM stuff with j Query too), so I decided to try and make a function to validate an email address without using Regex.We have a pre-made script that you simply paste in to your HTML.Once you’ve inserted our script onto your site, the real-time verification will be active on your website. Within minutes of updating your source code your email list will be more accurate than ever, giving your email marketing campaign the best chance of success.The drop down select list boxes usually will have one item saying ‘Select One’ (and that item will be selected by default).The user should select an option other than this ‘Select One’ item.
It adds an additional layer of security to your site, by doing this, you can immediately start sending out emails without worrying about deliverability issues.
