MailOptin vs OptinMonster (2026): which should you pick?

Pick MailOptin if

• 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

Look elsewhere if

• 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

Pick OptinMonster if

• Fits if you run a blog or shop and want more email sign-ups from it
• Works for agencies running sign-up campaigns across client sites, with sub-accounts from Pro

Look elsewhere if

• Skip it if you want exit intent on a budget, as it starts on Pro at $870 a year
• Not for you if you want to try it first, as there's no free plan or trial, only a 14-day refund
• Pricey if you budgeted on the first year, as Basic goes from $108 to $210 at renewal
• Watch out: going over the impression limit moves the account up to the next plan automatically
• Tight if you want geolocation, retargeting or store integrations, as all need Growth at $1,470 a year

MailOptin

• 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.

OptinMonster

• It does not build or host pages: it runs on an existing site where you can add JavaScript, with plugins and guides for WordPress, Shopify and others.
• First-year prices are introductory; Basic renews at $210 a year, and monthly billing costs $21 a month.
• Exit Intent, countdown timers and Zapier need Pro; geolocation, retargeting and store integrations need Growth.
• Going over the impression limit moves the account up to the next plan automatically; there is no free plan or trial, only a 14-day refund.
