How we grade them
| 2.4GPAOmnisendFair | 2.2GPAPostscriptFair | |
|---|---|---|
| Value for money | C$16 a month for 500 contacts, a little above the middle of what email tools charge, and $132 a month at 10,000. Paying 3 months upfront takes 30% off those months. Texts need Pro at $59 for 2,500 contacts and cost extra per message. | 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 | CFree for 250 contacts, 500 emails and 500 web push messages a month, with 24/7 support included. Enough to try the shop automations, not enough to run a store's email. | 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 | BReady-made store automations, an email builder that pulls in your products and discount codes, SMS and push, pop-ups, landing pages, shopper segments and ad audiences. It covers a store's whole job. Personalized content on Standard is an add-on from $5. | 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. The ready-made automations save time, but you'll still connect your shop and set up forms and segments in the web app. | 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. |

No desktop or phone app, and no public API is listed. | BRuns on the web, with Shopify, Klaviyo, Gorgias, Zendesk, Kustomer, Mailchimp, Omnisend and Triple Whale.
