Brand governance that holds
Define brands centrally — colours, fonts, heading styles. Lock the regions of a theme that must not change, so a template survives contact with fifty different authors.
A real drag-and-drop editor for people who send the all-staff email — wired directly into your own Gmail or Microsoft 365 account. Your address, your domain, your reputation. We never become the sender.
The difference
Mass-mail platforms relay your message through their own infrastructure. That is why internal announcements land in Promotions, show "via" beside your name, and get more expensive every time you hire.
Your all-staff email should look like it came from a person — because it did.
Everything else follows from that one decision: the deliverability, the pricing, the privacy posture, and what your works council has to say about it.
The editor
Three panes: components on the left, your email in the middle, properties on the right. It behaves the way you expect a design tool to behave — which is the whole point, because the person writing the all-staff email is not a designer.
Mark a section, and the table of contents at the top writes and re-orders itself. Long internal updates stop being a scroll.
Freeze the parts of a theme that must not move. Everyone else edits around them and the template still looks like your company.
Drop a two-option poll into the mail. Results appear in the campaign's analytics — as counts, never as names.
So it renders correctly in Outlook, which is still where most of your colleagues will open it.
What you get
Internal communications is not marketing. The controls are different, the audit expectations are different, and the privacy bar is higher.
Define brands centrally — colours, fonts, heading styles. Lock the regions of a theme that must not change, so a template survives contact with fifty different authors.
Nominate a reviewer and the send button stays locked until they sign off. Edit the content afterwards and the approval is automatically voided — nobody ships something a reviewer never saw.
Share a campaign as viewer or editor, publish themes across the company, and let edit locking stop two people overwriting each other mid-sentence.
Opens and clicks are aggregate counts. There is no per-recipient identity to disable, because the product was never built to collect one — which is a much easier conversation than a setting you promise to leave off.
Choose EU or US storage per customer. Set your own retention policy and old campaigns and tracking data delete themselves on schedule.
The details
Sign in with the Google or Microsoft account you already use. There is nothing to install, and no contact list to upload.
