Which one is for you
Pick Klaviyo if
- Fits if you run a Shopify shop and want emails driven by what people buy
- Works for brands that want email and texts in the same flows, with revenue shown per campaign
Look elsewhere if
- Pricey if your list grows fast, at $150 a month for 10,000 profiles, and the plan moves up by itself
- Skip it if you just want a newsletter, as that's a lot of store tool to pay for
- Tight if you stay free, since 500 sends a month is two emails to a 250-person list, and sending halts past it
- Watch out: texts cost extra per send, Composer AI past the allowance is $10 per 1,000 credits, and support packages start at $500
- Not for you if you want funnel and cohort reports without paying for the Personalization add-on
Pick Sendlane if
- Fits if you run a Shopify or WooCommerce store and want pricing by sends, not contacts
- Makes sense if you want email and SMS from one account
Look elsewhere if
- Pricey if you send little: the cheapest step on the page is $100 a month for 50,000 emails
- Watch out: SMS costs a $10 monthly activation plus credit packs from $6.25
- Not for you if you want a free plan, as only a short trial of 100 contacts and 500 sends exists
- Watch out: a banner says Privy has acquired Sendlane, so plans and pricing may change
- Skip it if you want a success manager without an annual contract

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
