| Pricing | Essentials from $100/month, billed monthly (5,000 profiles, 1M emails/month) · free tier: No free-forever plan; companies that have raised under $10M can get a full year free via the startup program.

| Best for | Funded SaaS or mobile product companies with 5k–100k profiles and engineering resource to send event data, who need email coordinated with push, in-app and SMS in one journey — especially startups eligible for the under-$10M free year. | Brands and agencies spending $4M–$35M+ per year on paid media, especially retail-media-heavy advertisers running Amazon, Walmart Connect, Instacart and Criteo alongside search and social, with high-volume repetitive build work across many accounts. |
| Avoid if | You want cheap newsletters, forms or landing pages, have no developer support for setup, sit on a large dormant B2C list you will still be billed for, need month-to-month flexibility above $100/month, or require phone-based billing escalation. | You spend under roughly $4M/year, run a single channel (Meta-only or Google-only), need best-in-class custom reporting as your primary requirement, depend heavily on newest Google surfaces like PMAX and Shopping, or lack onboarding capacity below the $756k white-glove tier. |

A higher TOP SCORE means more of the evidence favours that platform on this methodology — it is not a recommendation, and it does not account for your specific requirements. Advertisers are never declared the winner of a comparison.
