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 $40.83 a month billed yearly ($49 monthly). Carriers add a small fee per text, passed on without markup, and there's no automatic overage charge. That's ordinary for this category, and it says it will match SimpleTexting's prices.
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 14-day free trial with every feature and no credit card. Long enough to build a popup and send a first campaign.
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, with more automation than most: segments, branching workflows, popups, forms and landing pages, a two-way inbox and RCS. But texting is one channel of this category, and it only works in the US and Canada.
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.
CNo App Store rating on record. Every plan has the same features, but there's a number to register, which SlickText says often takes hours, and workflows to build.
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 Shopify, Mailchimp, HubSpot, Salesforce, Constant Contact, ActiveCampaign, Zapier and Make. Texts only reach the US and Canada, and there's no desktop app, which an A needs.
