Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.2
GPA, above 14 of the 54 other popup and widget tools we grade
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.
To get you started, here are 8 things to know about MailOptin, taken from its own pages and our grades.
It is a plugin you install and wire to an email service, with forms to build.

The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | No 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. |
| Free plan and trial | B | MailOptin 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. |
| Features | C | Popups, 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. |
| Ease of use | C | No store rating on record. It is a plugin you install and wire to an email service, with forms to build. |
| Platforms and integrations | C | WordPress only. It lists Mailchimp, AWeber, Constant Contact, ActiveCampaign, HubSpot, Brevo and Kit, but there is no app outside the site. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
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 it 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
Good to know
Good for
- WordPress sites that want popups and post-notification emails in one plugin
- Sites that want to try a free Lite edition first
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.
Part 02 · Pricing
What it costs
Every plan, the free plan, ways to pay less and how prices have moved
MailOptin's current pricing could not be confirmed from its own site.
MailOptin Lite is free on WordPress.org with popups, before and after post opt-ins, sidebar forms, page-level targeting and new-post emails.
We could not confirm MailOptin’s current prices from its own site, so this guide lists no plans. mailoptin.io has them.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.

Where this guide comes from
The prices, plans, platforms and features were read from MailOptin’s own pages on Nov 13, 2026, and the grades were given on Nov 13, 2026. 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.
Every tool we list gets five grades, A to F, each with its reason, and a GPA that averages them. How each is decided is at toolgpa.com/grades. This guide is ToolGPA’s own work; it is not made, paid for or approved by MailOptin. Prices change, so check mailoptin.io before you buy.
