Best for a free WordPress popup and newsletter plugin

MailOptin has a free Lite edition on WordPress.org with popups, opt-in forms and new-post emails. Premium prices could not be read, because the vendor's site put up a bot check, and spam protection and several conversion actions are premium-only. It runs only inside WordPress.

Who MailOptin is for

  • Fits if you run WordPress and want popups and newsletters from one plugin
  • Works for a small list that can live on the free Lite edition

Who MailOptin is not for

  • Skip it if your site is not on WordPress
  • Watch out: premium prices could not be read, so check them before you plan around Pro
  • Not for you if you want spam protection with reCAPTCHA or Turnstile for free: it is premium
  • Watch out: some broadcast audiences, such as membership or course plugin users, need the Pro version

Why MailOptin gets a 2.2

Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.

  • CValue for moneyNo paid price could be read, since the vendor's pricing page was behind a bot check, so we have nothing to grade against and it sits at the ordinary C.
  • BFree plan and trialMailOptin Lite is free on WordPress.org with popups, before and after post opt-ins, sidebar forms, page-level targeting and new-post emails. One person could run a small list on it.
  • CFeaturesPopups, forms, targeting, broadcasts and mail-service integrations in one plugin. The WordPress.org listing says reCAPTCHA or Turnstile spam protection and several conversion actions are premium, and some broadcast audiences need Pro.
  • CEase of useNo store rating on record. It is a plugin you install and wire to an email service, with forms to build.
  • CPlatforms and integrationsWordPress only. It lists Mailchimp, AWeber, Constant Contact, ActiveCampaign, HubSpot, Brevo and Kit, but there is no app outside the site.

What these grades rest on. Graded from this listing, whose facts were read from MailOptin's own pages on 13 November 2026. The vendor's site answered with a bot check, so its pricing page could not be read; the grades lean on the WordPress.org listing. Not based on using the product, and shorter than our full reviews.

Keep MailOptin, or make your own?

Keep it

To replace MailOptin you would be making newsletters sent to thousands of people that still reach the inbox. That is not a weekend's work, with an AI app builder or without one.

That makes this kind of software worth paying for, not this one in particular: 21 of the 54 other popup and widget tools grade higher.

What you could make

  • Popups and forms: an app builder makes these well.

What you could not

  • Newsletters sent to thousands of people that still reach the inbox.
  • It plugs into other products, Mailchimp, AWeber and Constant Contact among them.
  • Hooks into the device itself: widgets.

What this rests on. MailOptin’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.

What is MailOptin?

MailOptin is a WordPress plugin for popups, in-post and sidebar opt-in forms, notification bars and slide-ins. It also sends new-post notification emails and one-off broadcasts to WordPress users. A Lite edition is listed on WordPress.org; the premium edition's prices could not be read from the vendor site.

Worth knowing

  • Premium prices could not be read: the vendor's site answered with a bot check, so pricing is unverified.
  • Runs only inside WordPress.
  • Spam protection with reCAPTCHA or Turnstile and several conversion actions are premium-only, per the WordPress.org listing.
  • The listing says some broadcast audiences, such as membership and course plugin users, need the Pro version.
