In short
ProofBeer helps newsletter writers and publishers collect real customer feedback, bring in reviews from your own forms and social mentions and show them in widgets on their own pages, from one dashboard. Start free with no credit card.
Problems we hear from newsletter writers and publishers
Landing pages show only a sign-up form. Readers do not know if the newsletter is worth their inbox. Subscriber replies and tweets are scattered. Sponsors want proof of reader value.
How ProofBeer solves them
Collect: send a short 'what do you like about this newsletter?' form to subscribers and collect quotes with permission. Show: embed a carousel or grid on your sign-up page, and an avatar row next to the subscribe button. Sources: your own forms and social mentions can be synced into the same widgets as your own form responses.
Where to put proof
Sign-up landing page, about page, sponsor media kit page.
Recommended widgets
avatar row near the subscribe button, spotlight quote on the landing page, grid on an about page
Frequently asked questions
How do I get testimonials for my newsletter?
Send subscribers a short form asking what they like and what changed because of the newsletter, with permission to publish. Share it in an issue or a welcome sequence. ProofBeer collects responses and shows approved quotes in a widget on your sign-up page.
Where should I put testimonials on a newsletter landing page?
Put an avatar row or a short spotlight quote next to the subscribe button, and a carousel or grid below the benefits. Place proof where readers hesitate. Test one change at a time and compare sign-up rates before and after.
Can I use subscriber replies as testimonials?
Only with permission. Ask the reader if you may quote their email or tweet with their name or initials, and record the consent. Published quotes should keep the original meaning. Do not offer incentives for positive feedback only. This is not legal advice.
Can sponsors see subscriber testimonials?
You can create a testimonials or media kit page with a Wall of Love widget and share the link with sponsors. Combine it with your own audience stats, which should be accurate and current. ProofBeer's widgets are embeddable on any page that accepts custom HTML.
Is ProofBeer free for newsletter writers?
The Starter plan is free with no credit card and includes the form builder and widgets within limits, so a small newsletter can start at no cost. Pro adds more workspaces, automations and branding removal, with a 14-day money-back guarantee on paid plans.
