Create email signatures for a whole team from Excel

Updated 2026-08-05

Designing one signature is quick. Producing eighty of them, each with a different name, title, and direct line, and keeping the branding identical across all of them, is where it stops being a design task and becomes a data task. The reliable approach is to build the design once as a template and let a spreadsheet supply the variable fields.

Prepare the spreadsheet

One row per employee, one column per field that changes between people. Everything that stays constant — logo, brand colours, disclaimer, social links — belongs in the template, not in the sheet. Keep the header row exactly as the generator expects so columns map automatically.

1. Add a header row with the fields you want to vary: full name, job title, email, phone, mobile.
2. Fill one row per employee. Leave a cell blank to omit that line from that person's signature.
3. Check phone number formatting is consistent — signatures inherit the sheet exactly.
4. Save as .xlsx or .csv.

Blank cells are respected rather than rendered as empty rows, so employees without a direct line simply get a signature without one.

Build the template once

Set up the design with any single employee's details as a preview. Choose the layout, upload the logo, set brand colours, add social icons and any legal disclaimer. What you see in the preview is what every generated signature will look like, with only the spreadsheet fields swapped.

Spend the time here rather than after generating. Changing the logo after export means regenerating the whole set, which is cheap, but re-deploying it is not.

Generate and export

Upload the sheet in the Bulk panel and the generator produces one signature per row. The export is a ZIP containing, for each employee, the .htm file, the .txt plain-text fallback, and the image folder that Outlook expects — named to match the classic Outlook signature format.

1. Open the Bulk panel and upload your file.
2. Confirm the column mapping and review the row count.
3. Export the ZIP.
4. Spot-check two or three signatures before distributing.

Deploy across the company

There are three practical routes, in ascending order of effort and control. The simplest is to send each employee their folder with instructions to copy it into %APPDATA%\Microsoft\Signatures. The second is a logon script or Group Policy that copies the right folder to each machine automatically, keyed on username. The third is an Exchange transport rule that appends the signature server-side, which guarantees consistency including on mobile, but appends the signature at the bottom of the whole thread rather than under each reply.

Most organisations under a hundred people are well served by the first or second option.
