Boostmail vs the competition
Boostmail never charges per contact. You pay only for the emails you send, and the first 20,000 every 30 days are free, so there is no reason to prune your list. Most rival Shopify email apps bill by total contacts, so your cost steps up each time your list crosses a threshold, whether or not you send more. These comparisons break down what that difference means at real list sizes, and they are honest about the gaps: Boostmail is email only, with no SMS, no AI content and no visual flow builder, so a rival is the better pick if you need those.
Every claim on these pages is sourced from the competitor's own Shopify App Store listing or official pricing page, with the date it was verified, and any criticism appears only as a verbatim attributed merchant review, never as our own assertion. Competitor trademarks belong to their respective owners; this is an independent comparison, not an endorsement. When you are choosing an email app for your Shopify store, the right answer depends on your list size, the features you actually use, and how you prefer to pay, these pages give you the facts to make that call for yourself.
