Klaviyo vs Seventh Sense (2026): which should you pick?

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 Seventh Sense if

• Fits if you already send through HubSpot and want per-person send times
• Makes sense if you run Marketo and want to recycle engaged audiences

Look elsewhere if

• Not for you if you use neither HubSpot nor Marketo, because it works only with those two
• Skip it if you want to send email, as it does not send by itself
• Pricey if your list grows: $180 a month at 25,000 HubSpot contacts, and Marketo starts at $450
• Watch out: the page text shows $400 for 25,000 contacts while its slider computes $180
• Watch out: SSO, phone support and agency management start on Enterprise, from 150,000 contacts

Klaviyo

• The Free plan stops at 250 active profiles and 500 sends a month; sending halts until the next cycle or an upgrade.
• Price follows active profiles, and accounts move automatically to a higher plan as the list grows.
• Text and other mobile messages cost extra per send, priced by destination with carrier fees included.
• Composer usage beyond the plan allowance is billed at $10 per 1,000 credits; paid support packages start at $500 a month.

Seventh Sense

• It works only with HubSpot and Marketo and does not send emails by itself.
• The Business plan is billed annually and priced by marketing contacts, with no monthly billing shown.
• SSO, phone support and multi-portal or agency management are Enterprise features, which start at 150,000 contacts.
• The page text still shows $400 a month for 25,000 contacts, while the price slider computes $180 for that size.

Mobile messaging

SMS, MMS, WhatsApp, RCS and mobile push sit alongside email in the same flows, billed per message on top of the email plan.
