Omnisend vs Stensul

March's releases are dominated by a single coherent push: making Omnisend usable for agencies and multi-store merchants. The Partner Portal now supports Templated Accounts (build automations, campaigns, and signup forms once, copy them to many client stores), and a parallel batch of features lets users copy automation workflows, saved email templates, campaigns, and signup forms between accounts. The 'Managing Multiple Stores' update is the umbrella capability. Outside the multi-store push, two operationally important additions stand out: in-flight email campaign cancellation, and branded domains for form landing pages.

Omnisend is segmenting away from its single-merchant Shopify-app roots toward a two-tier product: solo merchants on one side, agencies and multi-brand operators on the other. The Partner Portal getting reusable templated accounts is the keystone — it changes the unit of work from 'one store at a time' to 'one configuration deployed to many stores'. This is a direct competitive move on Klaviyo Partner Network and Mailchimp's agency tooling. The cancellation feature and branded domains round out a respectability tier that enterprise-leaning customers will check for in RFPs.

Expect agency-pricing and partner-tier billing changes in the next few releases, plus deeper cross-store reporting (the natural follow-on to managing multiple stores from one console). The campaign-cancellation pattern likely extends to scheduled SMS and to in-flight automation pauses.
