Modes: Transactional And Marketing Are Separate Now

The sidebar opens with a mode switcher, and everything below it narrows to the one you picked.

Lettr does transactional email and marketing email, and until now both sets of navigation lived in one sidebar. Everyone saw twice the menu they needed and quietly filtered out the half that was not theirs. Nobody ever raised it as a problem, which is the difficult kind: a complaint you can act on, whereas people silently using less of your product is something you have to go looking for.

Shared links were the genuinely tricky part, because a campaign URL says nothing about which mode the person opening it was last in. Mode is inferred from the URL first and only then from what you last chose, so a pasted link lands correctly regardless, and the choice sticks between sessions afterwards. Switching mode switches context on the page you are standing on rather than throwing you to the start.

Analytics and Events now sit under Metrics together, an arrangement nothing was stopping us from choosing the first time. The layout was rebuilt against the designs while this was open, including a real mobile drawer — the previous mobile experience was the desktop sidebar, narrower.

A Dashboard That Knows Which Mode You Are In

The dashboard stopped showing one set of numbers to everyone; the mode now decides which cards render and what they count.

In transactional mode the usage card meters emails against your email limit and the analytics table breaks down by tag. In marketing mode it meters contacts against your contact limit, the traffic chart becomes bars on each campaign's send date, delivery performance gains click and unsubscribe rates, and the table becomes one row per campaign.

Transactional figures are computed by subtracting campaign volume from the totals rather than by filtering on a campaign id, specifically so that sends carrying no tag still get counted. An explicit Untagged row surfaces those instead of letting them vanish into a rounding difference.

Meet Adamko

An assistant in a drawer in the app that can read your account and act inside it, rather than a documentation search with a chat box on the front.

Asked which of your domains are ready to send, he lists them with the same readiness badge the Domains page shows. Asked why a sending domain is not verifying, he checks the live DNS himself and compares it against what the provider reports, then names the actual mistake — the record pasted at the wrong host, two SPF records, a CNAME flattened or proxied by Cloudflare, DMARC on the wrong host, a typo in the target. He is not permitted to call a record correct without a tool result in the same turn, and must quote every host and value verbatim rather than paraphrase one.

Where the right answer is a page in the app, he opens it instead of describing how to get there, and can run a pointer tour over the real interface — creating a domain or an API key, building a list or a segment, adding a webhook, or walking you to the event trail for a particular recipient.

Onboarding runs through him now. Ask him to set everything up, give him your website, and he reads it, shows you what he found, lets you choose which transactional emails you want, creates them, issues an API key and registers a sending domain — ending in a DNS walkthrough, since verification still waits on your registrar and on propagation. A guided setup that ends there is a fair improvement on what we had before, which was a checklist sitting next to a link to the docs.

Every tool he holds runs the same permission checks as the equivalent screen, so he cannot do through chat what your role forbids in the app. Every call is written to an audit log with its arguments redacted. An API key he creates travels only inside its own card and never through the model or the chat history. He is also banned from using emoji.

He is in beta and is being turned on team by team.

A Notification Centre

A bell in the topbar collects the things that finish while you are somewhere else.

A campaign finishing its send arrives with its recipient count and a link to it; an export becoming ready arrives with a download link. Announcements from us land in the same place rather than in your inbox.

Marketing Emails As A Card Grid

Marketing emails render as folders and thumbnails, with a toggle back to the table if you prefer it.

Folders became mode-aware with it, and the columns that only mean something for transactional email — slug, sent, opened, open rate — are hidden on the marketing side. The transactional list is unchanged.

A Redesigned Transactional Email Page

Settings on the left, a preview canvas on the right with desktop and mobile tabs and a language selector.

Name and subject save as you type. Version status moved into the header bar and turns green when a version is live, and version history opens as a drawer over the page rather than taking you somewhere else.
