How we grade them
| 2.0GPAAttentiveFair | 2.2GPAPostscriptFair | |
|---|---|---|
| Value for money | CNo prices are published at all: every plan is quoted after a demo, based on messages sent, list size, channels and AI tools. So there's no figure for 1,000 customers, and with nothing to compare it sits at C. AI Pro, AI Grow and AI Journeys cost extra on top. | CStarter has no platform fee, just a $49 monthly minimum spend. Texting 1,000 customers once at $0.009 per SMS stays inside that minimum, so $49 is the figure, plus US carrier fees averaging $0.0033 per SMS. That's the dear end of ordinary for this category. |
| Free plan and trial | FNothing free: no free plan and no self-serve trial. Sign-up goes through the sales team. | CNo free plan, but a free trial with a $100 credit toward message and carrier fees for your first 30 days. That's a decent run at a first campaign. |
| Features | BThe whole text-marketing job and more: SMS, MMS, RCS, email and push, two-tap sign-up on mobile, journeys for welcome, cart and back in stock, A/B tests, campaign reports and AI tools that write copy and pick segments and send times. | CThe texting job done fully for a Shopify store: campaigns, cart and browse abandonment flows, popups, two-way replies and segments built on order data. But texting is one channel of this category, RCS waits for Enterprise and email is still a waitlist. |
| Ease of use | CNo App Store rating on record. You can't just sign up: it starts with a demo and a quote, and then there are sign-up units, journeys and channels to set up. | CNo App Store rating on record. It plugs into Shopify, but you still set up opt-in popups, keywords and flows before the first text goes out. |
| Platforms and integrations | BWeb, with more than 100 integrations including Shopify, Salesforce, BigCommerce, Zendesk and Snowflake, plus APIs, and texts to customers in 20 or more countries. No desktop or phone app, which an A needs. | BRuns on the web, with Shopify, Klaviyo, Gorgias, Zendesk, Kustomer, Mailchimp, Omnisend and Triple Whale. API access waits for Professional at $500 a month, and there's no app. |
