    Sign up for free and copy your ProveSource code snippet from the Install Code page.

  2. Add the code to a landing page

    In MailerLite go to Sites → Landing pages and click Edit. Drag the Code block from Special onto the page, replace the placeholder with your ProveSource code and save.

  3. Or add it to a MailerLite website

    Go to Sites → Websites, click Edit and paste the code under Analytics and custom code → Header code injection, then save.

  4. Create your first notification

    Visit your page once so ProveSource detects the code, then create a Recent Sales, Counter or Review notification in your dashboard.

MailerLite and ProveSource: questions

Will ProveSource slow down my site?
No. The script loads asynchronously, so it never blocks your page from rendering.
Does it work on both MailerLite landing pages and websites?
Yes. Use a Code block on landing pages, and header code injection on websites.
Can I show notifications only on certain pages?
Yes. Each notification has display rules, so you can include or exclude pages by URL.
Is ProveSource free?
Yes. You can start on the free plan without a credit card and upgrade when you need more.
