signature a cinch

A signature freezes the moment it is pasted into a mail client. SigFinch stops fighting that — the artwork lives on our servers and the signature points at it, so a banner can change after it is installed.

Re: Contract review — Thursday

Happy to look over the draft before Thursday. I'll send comments tonight.

Kind regards,

Run php artisan migrate --seed to render the demo signature.

/b/harbour-finch/promo — never changes

Same signature, same inbox. Only the campaign behind the slot changed.

Three things stay put.
Everything else can move.

01

The URL is permanent

Every signature embeds a fixed address for its banner. It is baked into the HTML sitting in someone's mail client and it is never rewritten.

02

The campaign is not

What that address serves is decided when it is fetched, from whichever campaign is live. Schedule a date window and it swaps itself.

03

Caches expire in an hour

Long enough to be cheap, short enough that a change lands the same morning. Clicks are counted on the way through, as daily totals only.

Names and job titles are a different story — those live in the HTML itself, so a change there needs a re-copy. Everyone keeps a personal link that does it in one click.

Nobody sees more than they need to.

Staff never get an account. Managers never get the brand settings. We keep the keys to the layout gallery.

For your client

The portal

Owners set the brand and pick the layout. Managers add staff and schedule banners.

  • Brand and layout control
  • Staff list with CSV import
  • Campaign scheduling and clicks

For their staff

A personal link

No password, no account, nothing to reset. They fill in their details and copy it across.

  • Passwordless and durable
  • Live preview, light and dark
  • Step-by-step for six clients

For us

The back office

Provision a client, issue their logins, curate the shared gallery.

  • Client provisioning
  • Global layout gallery
  • Failed assets and stale signatures

Email is a hostile place to render anything.

Outlook renders with Word. Gmail cuts the message off past 102KB. Apple Mail refuses to recolour text in dark mode. Every signature that leaves here is checked against the things that actually break.

  • Tables, not flexbox Outlook ignores flex and grid, so the layouts never use them.
  • Circles baked in Avatars are cropped round in the file, because border-radius is ignored.
  • Retina by default Images ship at twice their display size and stay sharp.
  • Legible in dark mode Signatures carry their own light background so brand colours survive.
  • Padding, never margin Word drops margins on table cells, so spacing is cell padding throughout.
  • No web fonts Mail clients strip them, so only system stacks are offered.
