ConvertBox vs MailMunch (2026): which should you pick?

Pick ConvertBox if

• Fits if you'd rather pay once than keep a monthly bill going
• Works for showing different offers to people already on your email list

Look elsewhere if

• Skip it if you want to try before you pay, as the 14 days risk-free is a refund promise, not a trial
• Not for you if a lifetime deal that may close or rise without notice makes you nervous
• Tight if you outgrow 250,000 views or 10 sites, as the PRO upgrade's price shows only at checkout
• Watch out: its terms let it close any account, for any reason, with 30 days' notice
• Too light for working from a phone or desktop app, as there's none, and mobile popups need their own design

Pick MailMunch if

• Fits if you want pop-ups and a free email capture plan to start
• Works for Shopify stores that want to build a list

Look elsewhere if

• Watch out: the price comes from the Shopify listing, as MailMunch's own pages block reading
• Watch out: third-party sites quote other plan names and prices, so check before buying
• Pricey if your list grows, since Premium is $15 per 5,000 contacts and rises
• Tight on WordPress, where the free plugin needs a MailMunch account for premium features

ConvertBox

• The one-time deal is billed as early access, and the page warns it may close or rise in price without notice.
• Its terms let it close any ConvertBox account, for any reason, with 30 days' notice.
• The plan stops at 250,000 views a month on 10 websites; more needs the PRO upgrade, whose price is shown only at checkout.
• There is no free plan or free trial; the page offers to let you try it for 14 days risk-free.

MailMunch

• Its own pricing pages block automated reading, so these prices come from the Shopify App Store listing and may differ from the main site.
• Third-party sites quote other plan names and prices, so check the current pricing page before buying.
• The Premium price on the Shopify listing is per 5,000 contacts and rises as the list grows.
• On WordPress, the free plugin needs a MailMunch account for the premium features.
