This guide will show you how to take your sweepstakes and integrate it with Maropost so that you can start sending names and email addresses right into any Maropost list.

1) Connect to Maropost

When setting up your sweepstakes, go to the Connect Email Service section and click on Maropost.

2) Get your Maropost API Key and Account ID

Login to your Maropost account and in the top right corner click your name and then choose Connections. Your Account ID # is listed under the API document section (it should be the first thing on the page).

Next, click API Keys at the top of the page and grab your API Key. If you do not have one, click Add Key to generate a new one.

3) Input Credentials

Input your Maropost API Key and Account ID and click connect.

3) Choose a list

Once you successfully input your credentials and click the connect button, we will reveal your Maropost lists. Simply choose a list from the dropdown menu and click connect.

4) You're connected

That's it, you're all set. Your sweepstakes is now connected to your Maropost account, and we will send data right into that Maropost list.


If you have connected your sweepstakes to Maropost and email addresses are not being added to your list, these are the most common reasons as to why:

Email already in Maropost list
The email address entered into the sweepstakes may already be in your Maropost list, so it will not be added again.
Email already entered into ViralSweep
The email address entered into the sweepstakes has already been entered into the sweepstakes previously, so therefore it is not passed to Maropost. This can happen if you set up your Maropost integration after you have already entered the sweepstakes.
Delay in reporting
Maropost is having a delay in reporting. Try checking again in a few hours.
