What is the best OptinMonster alternative for you?

The best OptinMonster alternative depends on your needs, so let’s run through several scenarios:

If you want a more direct replacement for OptinMonster and you use WordPress, lead generation plugins such as Thrive Leads and ConvertPro are good options.

Both WordPress plugins include powerful page targeting features, drag & drop visual editors, and include plenty of integrations with popular email providers. They also support various types of opt-in forms.

Thrive Leads also has an accompanying landing page plugin called Thrive Architect.

If you don’t use WordPress, the best OptinMonster alternative is ConvertBox. There are many other SaaS alternatives, but ConvertBox is competitively priced and has some of the best targeting & segmentation functionality on the market.

If you’d like the addition of building landing pages, Unbounce is perfect – they have one of the best landing page builders on the market. They only support several opt-in form types though. And for those who would benefit from the addition of a website builder, Leadpages is worth considering.

What about a simple free OptinMonster alternative for WordPress? WP Subscribe is the best option and they have a paid plan to unlock more features.

For those who want a single tool to handle things like popovers, live chat, chat bots, and your entire email marketing – Gist is ideal.
