What it really isBDOW! (formerly Sumo) — website email-capture and conversion optimization toolkit.
Our takeSumo was acquired in December 2023 and rebranded as BDOW! in April 2024; the product now lives at bdow.com while sumo.com resolves to an unrelated service.
$39/mo is the monthly Pro price; annual Pro is $19/mo ($228/yr). A Starter plan at $25/mo also sits between the free tier and Pro. Core functionality — pop-ups, A/B testing, social sharing, and e-commerce tools — remains intact under the new brand, with expansion toward a fuller lead-gen suite underway.
Why we rate itThe genuinely free tier lets small sites test pop-ups with zero commitment.
A/B testing and e-commerce integrations on Pro offer real CRO muscle at a mid-market price — especially compelling at the $19/mo annual rate.
The catchThe free plan caps at 100 conversions/month and 500 emails — too tight for meaningful traffic.
The brand transition to BDOW! splits documentation and community resources across old Sumo and new BDOW properties, creating confusion.

Best / not good for

Best for
  • E-commerce stores wanting cart abandonment and pop-up tools in one platform
  • Bloggers and content creators building email lists on a budget
  • Small teams needing A/B testing without enterprise pricing
Not good for
  • High-traffic sites where per-plan pageview caps quickly become a ceiling
  • Teams needing built-in CRM or full marketing automation workflows
  • Enterprises requiring SSO, advanced compliance, or custom contracts
Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast — forms can be live within minutes of signup; no credit card needed for the free tier.
  2. Scale breakpoint
    Pageview caps per site and per-plan email limits become restrictive as traffic grows; multi-site costs compound quickly on the Plus tier.
  3. Walled garden
    Moderate — email lists and form data export is supported, but campaign workflows and analytics are platform-native with no open API for data portability.
Still a fit?
If none of these block you, start on the free plan.
