AI Email Writer

AI Email Writer that
scales your brand voice

Define how your team writes once. Teach the AI your brand, your products, your no-go zones. It applies them to every email - automatically.

Knowledge base

Everything the AI is allowed to say about you, in one place

Company profile

CompanyNorthpeakWebsitenorthpeak.io

What you offer

HR software for companies with 50 to 500 people. Onboarding, contracts and time off in one place, so nobody owns the admin as a job.

Who you sell to

HR managers and founders at companies hiring faster than their process can handle.

AI instructions

1Never mention pricing before a meeting is booked.

2Use a formal tone for public sector contacts.

3Never write “just circling back” or “touching base”.

4Answer in the language the contact wrote in.

5Keep every email under 120 words.

Plain-English Instructions

Write the rules in your language. AI follows them.

No syntax to learn. You write the rules the way you would say them out loud, and it shows you what it understood before it enforces anything.

  • Scope rules to org, agent, or specific sequence
  • Auto-clarification loop: parser asks if a rule is ambiguous
  • Visible parser output: see what the AI will actually enforce
  • Negative guards auto-injected for conditional clauses
Custom instructions6 rules

You wrote

“Never mention pricing before a meeting is booked.”

What it will enforce

If no meeting is booked then do not mention pricing

If a meeting is booked then pricing is allowed

The opposite case, written for you. You only gave it one half.

“Keep emails short.” Short how? Give me a number and I will hold every email to it.

Compliance Built-In

Every email validated against your rules before send

Every email passes a pre-send validator. Banned phrases are blocked. Conditional clauses fire on matching contacts only, and explicitly inject negation when they don't apply, so the AI never accidentally mentions what shouldn't be there.

  • Phrases you ban never leave the building
  • Conditional clauses: if/then matched per contact
  • Approved brand mentions: competitor names auto-filtered
  • Every email comes out in the contact's own language

Your clauses, against this contact

If the contact works at a partner brand then mention the partnership

If the company has fewer than 50 people then leave out the enterprise case studies

If a competitor came up in the thread then do not name them, talk about payback instead

Added to this email’s instructions

Do not mention any partnership to this contact. She does not work at one of the brands.

Quality Validator

No email sends with an unresolved merge tag

No customer will ever receive an email starting with "Hi {{first_name}}". Anything with a placeholder still in it, or missing something it needed, is held back and written again.

  • A placeholder left in the text holds the email back
  • Last-viewed guard, never approve an email that changed after you saw it
  • Rewriting in bulk asks you what was wrong, and it learns from it
  • Anything you approved by hand is never overwritten
Last check before sendevery email, every time
