Editorial standards

The Bannerly Team — Product & editorial, Bannerly. We build Bannerly's banner editor. Every guide here is written against the product we maintain and checked in real email clients before it is published.

Anything we say about how a banner behaves in an email client has been checked by exporting a banner from the Bannerly editor and sending it to real accounts. The last full re-check of the client support table was 2026-08-21.

• Banners are exported from the live editor, not mocked up.
• Each export is viewed in Gmail (web and mobile), Apple Mail (macOS and iOS), Outlook on the web, and Outlook for Windows.
• Where behaviour differs between clients, we say so in the guide rather than describing the best case.
• Guides carry a “What we tested” note describing exactly what was checked.

• No invented statistics. We do not publish conversion or click-rate figures we have not measured ourselves.
• No fabricated testimonials, ratings, awards or customer counts.
• No product features that do not exist. Everything described in a guide can be done in the Bannerly editor today.
• Where a claim comes from a third party — a mail client vendor, for example — we link to the source.

Every guide shows the date it was last updated. Email clients change, so we re-check the support table periodically and revise guides when behaviour moves. If you spot something wrong, tell us at [email protected] and we will correct it and note the change.
