Serverless email forms for no code or JAM Stack static sites

Just POST any HTML form to:

https://api.mailslurp.com/forms<em>?_to</em>=<strong>you@mail.com

Form fields are sent directly to your inbox seconds later. Even attachments!

Basic usage

Include any form fields you like, MailSlurp will create a table with the data and email it to the email address provided by the _to query parameter or form field name.

<form action="https://api.mailslurp.com/forms?_to=YOUR_EMAIL" method="post">
  <!-- include any form fields, even files -->
  <textarea name="example"></textarea>
</form>

When the form is submitted MailSlurp determines the _to email address and emails the form data and files to the address.

Configuration options

You can control behavior of the form and email using meta parameters. The parameters tell MailSlurp how to handle the form and can be supplied in the URL or as hidden form inputs.

Example

Here is an example where the _to email address and _subject are specified as hidden form fields.

< action="https://api.mailslurp.com/forms" method="post">
  <!-- hidden meta parameters -->
  <input type="hidden" name="_to" value="you@mail.com">
  <input type="hidden" name="_subject" value="Customer contact">
  <!-- (spam check field, leave empty) -->
  <input type="hidden" name="_spamCheck" value=""/>

  <!-- visible meta parameters -->
  <!-- (_emailAddress allows you to reply to the submitter directly) -->
  <input name="_emailAddress" type="email" placeholder="Customer's email">

  <textarea name="message"></textarea>
</form>

All meta parameters

Mask your email address

Protect your email address from spammers and bots by using an email alias. Create a MailSlurp email alias then use the ID in a _toAlias parameter.

<form action="https://api.mailslurp.com/forms" method="post">
  <!-- hide email with an alias -->
  <input
    type="hidden"
    name="_toAlias"
    value="9b32cb34-e75a-48a6-8f6c-817204c354e7"
  />
  <!-- data to submit -->
  ...
</form>

Reduce spam

Include a special <input type="hidden" name="_spamCheck"> field in your form to catch out bots and reduce spam. (MailSlurp will discard submission that fill the hidden field.)
