How we grade them
| 2.2GPAPostscriptFair | 2.4GPASimpleTextingFair | |
|---|---|---|
| Value for money | 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. | C1,000 credits, enough to text 1,000 customers once, is $39.20 a month billed yearly ($49 monthly). A local number adds $10 a month and $4 to register, and carriers add about $0.0025 a US text. That's ordinary for this category. |
| Free plan and trial | 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. | CNo free plan, but a free trial with no credit card. It has you text your own number first, so you see how a campaign lands before paying. |
| Features | 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. | CThe texting job done fully: mass texts and MMS, two-way replies, unlimited keywords, forms and pop-ups, auto-replies, drip campaigns and an AI writer. But texting is one channel of this category, with no WhatsApp or Instagram. |
| Ease of use | 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. | B4.68 from 3,487 App Store ratings, just under the 4.7 an A needs. Every plan has the same features, so there's no tier puzzle to work out either. |
| Platforms and integrations | 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. | BWeb, iPhone and Android, with Mailchimp, Zapier, Calendly and the API on every plan. No desktop app, which an A needs. |
| Best for | SMS marketing for Shopify stores | mass texts and replies for small US businesses |
