Bring in the people

Pull straight from your employee directory, or upload a CSV or spreadsheet where each row is one recipient.

03

Map the merge fields

Name, role, salary, dates and anything else drop into the right place for every letter at once.

Generate and download

Every letter comes out personalised, bundled together and ready to send, in one run.

Built for volume

What makes it good

The point is scale without the copy-paste. Give it a template and a list of people, and it does the repetitive part for you.

Real mail merge

One template plus a directory or spreadsheet becomes a personalised letter for every single row, not a copy-paste chore.

AI-templatised

Paste any letter you already use and the AI finds the variable bits and converts them into clean merge fields for you.

Country-aware

Works for teams anywhere. Letters follow the location and language conventions of the people you are writing to.

Bundled output

Finished letters are packaged together so you download the whole batch in one go, ready to distribute.

Who it’s for

One generator, several jobs

HR & people teams

Sending appraisal, increment, confirmation or transfer letters to a whole department in a single pass.

Founders & small businesses

Rolling out offer or onboarding letters to a new cohort without hand-editing each one.

Operations & shared services

Producing consistent, on-brand documents across sites and entities at scale.

HR consultants

Turning around a batch of letters for several clients without rebuilding a document each time.

The complete guide

How mail merge works for HR letters

Template plus data equals many letters

A mail merge takes one letter written with placeholders and fills those placeholders from a list of people, producing a separate, personalised document for each row. Instead of opening a file, changing the name and salary, and saving it again for every employee, you set up the letter once and the tool generates the whole batch. The saving grows with team size: the same effort covers ten letters or a thousand.

Where the data comes from

You can drive the merge from your existing employee directory, so names, roles, dates and pay flow straight in, or from a CSV or spreadsheet you upload, where each row is one recipient and each column is a field the letter can use. Pasting an existing letter is enough to get started; the AI reads it, works out which parts change from person to person, and turns those into merge fields you can map.

What you can send in bulk

Almost any repeatable HR document fits the pattern:

Letter typeTypical merge fields
Offer & appointment lettersName, role, start date, compensation, location.
Appraisal & increment lettersName, new package, percentage change, effective date.
Confirmation & probation lettersName, role, confirmation date, reporting manager.
Transfer & promotion lettersName, old and new role, team, effective date.
Experience & relieving lettersName, tenure, role, last working day.

Consistent, and quicker to check

Because every letter is built from the same template, the wording, formatting and branding stay identical across the batch, so the only thing that varies is the merged data. That makes a large run far easier to review than a folder of hand-edited files, and it removes the small copy-paste slips that creep in when the same document is edited over and over. Generate the set, scan the merged fields, and download everything together.
