| Pricing | From $20/month (Email plan, 251–500 active profiles) — provisional, third-party sourced · free tier: Up to 250 active profiles, 500 email sends and 150 SMS/MMS credits per month; email support for the first 60 days only | 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. No trial length published. |
| Pricing model | Subscription (tiered on active profiles) plus paid add-ons | Subscription with usage-based overages |
| Best for | Established Shopify, Magento or custom-store ecommerce brands with high revenue per subscriber and disciplined list hygiene, who will use deep store-data segmentation to earn back a premium, variable bill. | 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. |
| Avoid if | You need a fixed, predictable budget, run a large low-engagement or non-opted-in list, send high-volume batch campaigns against a cap, are a non-ecommerce B2B or newsletter sender, or need responsive human support at entry-level spend. | 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. |

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.
