It's her email, not a lookalike
No relay address and no “via” line. It is signed by your own domain and follows the same route as every other internal message, so it lands where internal mail lands — not in Promotions.
Built to brand in a real editor, then handed to your company's own Gmail or Microsoft 365 account to deliver. We are never the sender — which changes the deliverability, the pricing and what the tool is able to know about your staff.
A campaign built in SlipperySign, delivered by the sender's own mailbox, as the recipient sees it.
Q3 all-hands: what changed, and what's next
Team — a short summary of where we landed this quarter, and the three things changing in October.
Everything below is also on the intranet, but I wanted you to have it directly.
No relay address, and no “via” line beside her name. It is her mailbox, so it is simply her email.
Into her inbox, in the same thread. If IT would rather they landed in a shared mailbox, a Reply-To address sends them there instead.
It travels the same path as every other internal mail, so it arrives where internal mail arrives.
Because she sent it. There is no separate system of record to reconcile at audit time.
Every one of these exists because the mail leaves your own mailbox instead of ours. That single decision is what the rest of the product is built on.
Identity
No relay address and no “via” line. It is signed by your own domain and follows the same route as every other internal message, so it lands where internal mail lands — not in Promotions.
Replies
By default straight back to the sender's own inbox, in the same thread, where she can actually answer them.
If your IT would rather route them to a shared mailbox — comms@, hr-support@ — set a Reply-To on the campaign and answers land there instead.
Optional · your IT decidesAuthoring
Drag components onto the canvas: text, image, button, section, poll. Mark a section and the table of contents reorders itself. Output is MJML, so it survives Outlook.
Brand control
Freeze the masthead, the footer, the legal line. Everyone edits around them, and the hundredth campaign still looks like the first one. Brands are managed centrally; the standard brand cannot be edited by a customer, only duplicated.
Governance
Send stays locked until the named reviewer signs off, and any edit afterwards voids the approval. Share a campaign as viewer or editor, with a check-out lock so nobody overwrites anyone mid-sentence.
Measurement
Opens and clicks are totals, plus a per-day rollup and a per-link count. There is no recipient column anywhere in the tracking tables, so a per-person report cannot be produced — by us, or by an employer.
Properties on the right, including the regions you have locked. Built on MJML, so what you assemble here is what Outlook renders.
The first number is a property of the database schema, not a promise. The second half is the honest half: this tool is not a zero-data tool, and it would be misleading to sell it as one.
recipients we can name Across every campaign, every open, every click, for every customer.
Opens are one counter per campaign. Clicks are one counter per link. There is a per-day rollup, and that is all. There is no table a per-person report could be built from.
Campaigns are addressed to the distribution lists and group aliases you already have. Your mail provider expands them at send time — we never see the membership.
There is no password field and no password store. Google or Microsoft authenticates the person and hands us a verified email address.
We would rather you read this here than find it in an audit. This is the complete list of personal data in the system.
Subject, content, the From name and address, the Reply-To if you set one, the BCC field if you use it, and the list address it was sent to.
The email address of the campaign's owner, of anyone it is shared with as viewer or editor, and of whoever granted that access.
The group addresses you save for reuse, and the email addresses of your company administrators.
Who did what, and when — including any occasion a platform administrator acted on behalf of a user.
We store the address you send to. Addressed to a distribution list — which is how the tool is meant to be used — that is one address, not your staff.
Retention is set per customer. Campaigns and tracking detail delete themselves on that schedule, and residency is EU or US per customer record.
Answered here rather than in a follow-up call, because the answers are short.
Sign in with the Google or Microsoft account you already have. Nothing to install, and no contact list to upload.
