Marks, colors,
type, voice.
Everything you need to write about Warmbly, build an integration, or place the logo on a slide. Free to use without asking, with one rule. Do not imply a partnership we have not agreed to.
Four official lockups.
Wordmark and standalone mark, each in a light and dark variant. Use the variant with the highest contrast against the background. Nothing else is an approved usage.
- Wordmark for sign-off, footers, partner pages.
- Mark for favicons, avatars, app tiles, OG cards.
- SVG everywhere it is supported. PNG at 2x for raster only.
The mark holds up at 16px because the angles are simple. Below 16px, use the favicon variant in /brand/favicon.ico instead.
The profile picture.
The Warmbly profile image used across X, LinkedIn, GitHub, Product Hunt, and other social surfaces. Square crop, sky background, mark centered. Use this exact file rather than recreating it at runtime.
- Source resolution is 1024 by 1024.
- Safe for round and square crops. The mark stays inside the inner 70 percent.
- Do not overlay text. Do not recolor the sky.
round · 48 round · 64 square · 80 square · 112 The mark sits within the inner 70 percent of the canvas, so the silhouette survives circular masks on profile chips.
Sky ramp. Plus a neutral system.
Ten steps from atmosphere to deep sea. Sky-600 is the primary brand color used on links and action buttons. Sky-700 is the hover state. Everything else is composition.
Inter for everything. System mono for code.
One typeface keeps the marketing site, app, and docs in the same voice. Sizes follow a small ramp tuned for tight tracking at large display sizes and relaxed leading at body sizes.
Self-hosted via @fontsource/inter. Used for every UI surface, every headline, every body paragraph.
ui-monospace, 'SF Mono', Menlo, monospace. No web download. Used for code snippets, metric labels, and timestamps.
Most cold-email platforms reward you for sending more. Warmbly rewards you for sending well. Mailbox caps default to fifty a day. Workers are capped by the sum of their mailbox budgets, not an arbitrary global number. The defaults exist because the inbox is a finite resource.
// Schedule a send respecting the per-mailbox cap.
scheduler.scheduleSend({
mailbox: "ben@acme.com",
campaign: "cmp_2025_q2",
cap: 50, // emails / day
gap: 600, // seconds between sends
});How Warmbly sounds.
Plain English. Short sentences. Numbers when they matter. If a line could come from any other SaaS site, rewrite it.
No promo wrappers. No tracked images by default. Cold mail should look like a real message from a real person, because that is what it is.
Fifty sends a day. Ten minutes between messages. Warmup starts at ten. The defaults are where a healthy mailbox lives, not a starting line to sprint from.
No fabricated open rates. No screenshot leaderboards. If a metric is on the page it came from your account or the open-source repo.
We talk about workers like servers, not heroes. One worker, one IP, a few mailboxes. Volume scales by adding workers, not by overloading one.
Logo guardrails.
A few things to do, and a few things to leave alone. The mark is simple on purpose. Effects, recolors, and combo lockups undo that on purpose.
Keep at least the height of the mark as padding on every side.
Use the foreground mark on white surfaces. Wordmark in slate-900.
On any sky-700 to sky-900 background, switch to the white mark.
On photography or video, use the solid white or solid foreground variant.
The wordmark and mark are fixed proportion. Never squash or skew.
Use the foreground, white, or sky-900 variants. No off-brand color fills.
No drop shadows, no glows, no outlines, no gradients applied to the mark itself.
Do not combine the Warmbly mark with another logo into a single wordmark.
Always Warmbly. One word. Capital W.
In running prose, refer to the company as Warmbly. Refer to the product as Warmbly or as the Warmbly platform. Avoid possessives on the wordmark itself in logo contexts.
