It integrates with Shopify, BigCommerce, WooCommerce, Magento, Wix and Square Online, and runs hosted MCP servers so AI assistants can call its tools. Endpoints cover campaigns, automations, contacts, segments and email templates. APIs.io catalogs 13 workflows for it, including 'Subscribe and Trigger Welcome' and 'Create and Send Campaign'. Omnisend offers a free tier with self-serve signup, authenticated via API key or OAuth token. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I add a new email subscriber or update them if they already exist using Omnisend's API? Use the POST /contacts endpoint, which adds a new subscriber or updates the existing contact if the email address is already present. A separate PATCH /contacts endpoint can also update a contact using only their email address, without needing other identifiers. _Developers wiring up ecommerce signup flows can track API patterns like this on daily.dev._ ### Does Omnisend support MCP servers for AI assistants? Yes, Omnisend runs hosted MCP servers, the connector standard AI assistants use to call tools. This lets an AI assistant add subscribers, build segments, and send campaigns directly through Omnisend's API rather than requiring manual list copying between systems. _Anyone connecting marketing platforms to AI agents can follow MCP adoption news on daily.dev._ ### How can I find out how many contacts currently match a given customer segment in Omnisend? Call GET /segments/{segmentID}/statistics, which returns how many contacts match that segment's conditions right now. Segments themselves are created with POST /segments from a set of conditions, and GET /segments/{segmentID} shows the conditions behind an existing segment. _Developers building segmentation logic can keep up with marketing API capabilities on daily.dev._ ## Similar posts on daily.dev - [Best Email Marketing Automation Tools for Building a High-Converting List](https://daily.dev/posts/best-email-marketing-automation-tools-for-building-a-high-converting-list-tgm2bnfnf) · Ruby Flow · 0 upvotes · 0 comments - [Unosend: One API.
