How to use:
If you need to check if one or more email addresses are valid, that is, if the formatting and the domain exist, enter the emails (or just one) in the email field. Bubble's default check only checks if the input is formatted as an email, that is, without spaces, without commas, with an at sign, etc. This plugin's check is more powerful, as it checks if the domain really exists. To do this:

Use the action: 'verify domains' available in the plugin. Store the result of these actions in some custom state.

The results of this action are:

is domain valid? Informs if the dom

If you need to check if an email is deliverable, that is, if it can receive emails, you will need a Zero bounce API key, which is very simple to obtain.

1- Go to https://www.zerobounce.net/members/API and create a free account.

2- Copy your API key and paste it into the plugin.

Note that when you register you get 5 free credits to use in the plugin. To add more credits, you can buy them (which is cheap). Currently, in March 2025, their package with the right to 2,000 checks costs $18 (0.009 per credit). 1 Credit = 1 Email verification.

After pasting your API key into the plugin, insert the 'email verifyer' element into your bubble editor and enter the email address you want to verify and the result will be available in the state: is email valid? like yes or no and no state email details the check details.
