Updated over a week ago

How it works

Inbox works just like a regular email inbox, but smarter and tailored for requests for proposals (RFPs). Some of the highlights:

  • Convert requests to proposals in seconds – 3 simple clicks are all you need

  • Works with any website form – use your current design & logic

1. Getting started

Activate Inbox

To get Inbox activated on your Proposales account, send a request to our Customer Success team. You'll know when Inbox is activated by going to and checking if Inbox is listed as an active integration.

Once Inbox is activated on your account, copy the address to your inbox from the details and use it when connecting your website forms with Proposales. (It contains your inbox_token)

2. Integration process

Connect with your HTML website form

Inbox works with any website form, simply replace the address where your form should be posted. No visual changes are needed.

<form action="{inbox_token}" method="POST">
   <!-- Your input fields -->

Default fields

Make sure to name your input fields like this:

  1. first_name 

  2. last_name 

  3. email (we recommend to use type="email"  for this input)

  4. company_name  (optional)

  5. phone_number  (optional)

  6. message  (optional, displayed in request excerpt)

3. Extras

Custom fields

Inbox works with unlimited custom fields, simply name your additional <input> fields and it's content/value will be collected to the request.

<!-- Example 1 -->
<input name="number_of_guests" type="number" value="" />

<!-- Example 2 -->
<input name="arrival_date" type="date" value="" />

<!-- Example 3 -->
<select name="pet">
    <option value="dog">Dog</option>
    <option value="cat">Cat</option>

Submit redirect

If you're using a regular POST submit you can still set up a redirect to a specific website address on success:
<input name="redirect" value="" type="hidden" /> 

Custom language

The default language is English, however, you can override that with another language so that confirmation emails will be in your preferred language. Here’s an example for sv (Swedish):
<input name="language" value="sv" type="hidden" />  

Custom webhooks

Get in touch with us if you want to set up custom webhooks – possible anywhere between the request and accepted proposal.

Available events:

  • Request submitted 

  • Proposal created

  • Proposal sent 

  • Proposal viewed 

  • Proposal accepted / Proposal rejected
