Apple Mail · macOS Tahoe 26 / Sequoia 15 · No Mailbox Access
Build and preview a clean signature in SignPack, then add the visible content in Apple Mail's official right-side signature editor. The guide below follows the current macOS Tahoe and Sequoia settings flow, including account assignment and default-signature selection. No signup, Apple ID connection, or mailbox access.
5 Apple Mail setup steps
Apple's current flow creates the signature inside Mail, edits it in the right column, and assigns it to an account from the middle column. It does not document a Finder .htm import. Review the current Apple Mail signatures guide alongside these SignPack-specific notes.
In Mail on your Mac, choose Mail > Settings, then click Signatures. In the left column, select the email account that should use the signature. You can also start in All Signatures if you plan to reuse one signature across accounts.
Why this works
Apple documents the left column as the place to choose All Signatures or a specific email account. This keeps the signature attached to the intended sender identity.
Click the add button below the middle column, then give the new signature a clear name. If you created it under All Signatures, Apple requires you to assign it to an account before you can use it.
Why this works
The middle column is Apple's official list of signatures. SignPack does not currently download a .htm file or provide a file-import action for Mail.
Build and preview the signature in SignPack, then use that result as your content and layout reference. In Mail's right column, enter the signature text, format it, add links, and drag in an image when needed. SignPack's Copy clean HTML action copies the source markup; Apple Mail's documented settings do not include a raw HTML or .htm import command.
Why this works
Apple identifies the right column as the supported editor and preview. Keeping the limitation explicit prevents raw HTML tags from being mistaken for a rendered signature.
If you created the signature under All Signatures, drag the signature from the middle column onto the destination account in the left column. Repeat that assignment for every Mac Mail account that should use the same signature.
Why this works
Apple's documented drag action moves an existing signature from the middle column to an account in the left column. It does not import an HTML file from Finder.
Use Choose Signature to select the default for the account, or choose sequential or random rotation if that is intentional. Then send test messages to Gmail, Outlook, and another Apple Mail inbox. Check links, images, spacing, and wrapping on desktop and mobile before rollout.
Why this works
The default selection controls whether Mail inserts the signature automatically. Cross-client test messages reveal rendering differences before customers see them.
Open Mail > Settings > Signatures, select an account, click the add button, and edit the signature in the right column. Apple documents that editor for text, formatting, links, and images. SignPack currently copies clean HTML source and does not provide a .htm download or a direct Apple Mail import.
SignPack's current Copy clean HTML action copies source markup. Apple Mail's documented signature settings do not expose a raw HTML or .htm import command, so SignPack does not promise a one-click rendered paste. Use the SignPack preview as a reference, then create the visible signature in Mail's right-side editor.
Apple says this option makes the selected signature use the message font configured in Fonts & Colors settings. Leave it enabled when you want the signature to follow that default; turn it off when you want to keep formatting chosen in the signature editor.
Create the signature while All Signatures is selected. Then drag that signature from the middle column to each account in the left column. Apple says the same signature can be used in multiple accounts.
Apple says iCloud Drive can make Mail signatures available on other Mac computers that also have iCloud Drive enabled with Mail selected. Apple's current guide does not make the same promise for iPhone or iPad signature settings.
No. SignPack builds and previews the signature in your browser and does not access Apple Mail, your Apple ID, or your mailbox. The current free action copies clean HTML source. Team Lite ($15/month) adds a saved master template and up to 10 employee variants without mailbox access.
Team Lite ($15/month) keeps one approved master template and up to 10 employee variants organized before each teammate creates the visible signature in Mail. The rollout notes cover the current right-side editor, account assignment, default selection, and cross-client test path without requesting mailbox access.
Single-person use stays free. Team Lite is the only paid tier.
Team email signature install packs without mailbox access.
