What's new
New products, new features and the improvements you asked for. Building on the API? The developer changelog is in the docs.
October 2026
- Platform
Everything is live
Every product is now available to every workspace. Turn on what you need from your workspace settings — there is nothing to request or wait for.
Learn more - Email API
Email API, inside your workspace
Send receipts, sign-in codes and notifications from your own apps without leaving your workspace. It sends from the domain your workspace already verified.
- API keys with sending-only or full access
- A delivery log for every message, with bounces and complaints
- Webhooks and a suppression list shared with Marketing
- Automation
Automation: workflows and AI agents together
Workflows and AI agents now live in one place. Build workflows that branch, loop and merge, and let an agent do the steps that need judgement — with budgets and approvals.
- If, switch, loop, split, filter, aggregate and merge steps
- Test any single step with sample data before you turn it on
- HTTP steps that use saved credentials
- A templates page to start from a working automation
- Try an agent in a playground before you give it a job
- Sites
Sites: quick pages at sites.mercestack.com/you
Make a link-in-bio page, an announcement or a bio in minutes from a template, share it at sites.mercestack.com/your-name, or point your own domain at it.
- Starter templates for link pages, launches, events and more
- Looks right on phones and desktops
- Sign-ups from your page land in your CRM
- Marketing
Designed marketing emails
Campaign emails now start from real designs — letters, banners, newsletters and posters — in eight colour themes, with a preview and the HTML a click away.
- Each plan includes marketing credits every month
- Growth — loyalty, referrals and offers — now lives inside Marketing
- AI ad drafts turn your real numbers into a strategy or an ad, and an approved draft becomes a campaign or a social post
- Workspace
A new look for Huddle, Mailbox and Work
Cleaner screens for the places you spend your day.
- Huddle: message actions appear when you hover, not under every message
- Mailbox: avatars, clear unread markers, and the customer beside the thread
- Work: a sprint progress ring, project cards with progress, and one-click done
- Analytics
Analytics that compare periods
Revenue, orders, customers, leads, bookings and work over time, each compared with the period before, with a table view for every chart.
- Forms
Forms with designs
Give a form a theme, a font, a cover image and a layout — cards, a single sheet, or one question at a time. Forms you no longer need can now be deleted.
- Apps
Apps: see what Mercestack already replaces
Search the tools you use today and see which product in your workspace already does that job — and connect the few it does not.
