Generic AI email tools cannot see your candidate. You can

Most "AI email" tools are general-purpose writers. They produce competent prose, but they have no idea who you are emailing. The candidate's resume, the role they applied for, the interview notes from last Tuesday, the job notes you wrote about hiring priorities: none of that is reachable from Grammarly or Mailmeteor.

So either you copy-paste each candidate's context into ChatGPT every time, or you fall back to generic templates and the email reads like a bot wrote it. Both options waste time, and rejection emails to candidates who interviewed twice end up sounding cold.

How 100Hires AI Email Composer works

The AI Email Composer lives inside the candidate Messages tab, next to the "Insert email template" button. Click it, pick a saved prompt (or type a custom instruction), and the AI drafts the email using everything the platform already knows: resume, application answers, email history, evaluation forms, job description, job notes, interview discussion notes. Review, edit, send.

For the most common use cases, save the prompt once and reuse it forever. "Polite rejection with positive traits", "Schedule interview email", "Follow-up after no-show", "Recruiter intro for senior engineer": each becomes a one-click action that produces a candidate-specific email, not a templated one.

AI Email Composer saved prompts dropdown with balanced side margins

Saved prompts. One click. Personalized email

Pick a prompt from the dropdown, hit Generate, and the AI writes the email referencing the candidate by name, by role, by what they actually said in the interview. The first draft lands within 5 seconds. Edit if needed, send.

  • Saved prompts library, sorted by recency
  • Frontier-class AI model, refreshed as better ones ship
  • Inline in the Messages tab, no separate AI app or browser extension

A prompt library that compounds with your team

Build prompts for the emails you write 10 times a week: rejection after final interview, schedule the second-round panel, follow up on a stalled offer, intro to a passive candidate sourced through LinkedIn. The library is shared across your company, sorted by recency, and editable. The team adds prompts as workflows evolve, so the prompts your senior recruiter saves are immediately available to junior recruiters and hiring managers.

  • Shared company prompt library
  • Add, edit, delete from Settings > AI Prompts > AI Email Composer tab
  • Most-recent-first dropdown so the prompt you used 5 minutes ago is still on top
AI Transform dropdown menu with Grammar, Rephrase, Friendly actions above Send Email

Already drafted? Transform it instead

If you started typing the email yourself and want help finishing it, three transform actions are one click away in the email composer toolbar. Grammar fixes typos and grammar without changing the meaning. Rephrase keeps the message intact but reworks the sentences. Friendly softens the tone for candidates who need a warmer touch.

  • Grammar - fix typos and tighten sentence structure
  • Rephrase - rewrite the same idea in different words
  • Friendly - shift the tone warmer without losing professionalism

Stop copy-pasting candidate context into ChatGPT

The rejection email use case nobody else handles well

A candidate spent 3 hours of their week on your interview process. They prepared, they showed up, they answered honestly. Then you reject them with a 4-line template that starts "Dear [First Name]" and ends "we will keep your resume on file". They will remember that experience. They will tell other candidates.

The AI Email Composer reads the actual interview notes the team wrote, the application answers, the resume highlights, and writes a rejection that mentions specific strengths the candidate showed. The candidate gets a paragraph that reads like a person on the team paid attention to them. It takes the recruiter 30 seconds instead of 30 minutes.

Templates from a typical ATS cannot do this. They have no read access to the discussion notes. The 100Hires AI Email Composer does, because it sits inside the same product that holds the notes.

How 100Hires AI Email Composer compares to generic AI email tools

The "AI email tool" category includes everything from Grammarly to Mailmeteor to ChatGPT itself. They are excellent at generic writing. They do not know your candidate. Here is the tradeoff.

Where 100Hires AI Email Composer is not the right tool: if you write 5 candidate emails a year, generic AI assistants are cheaper and good enough. If you write 10 a day, the ROI flips fast: the AI saves about 5 minutes per email vs. writing it from scratch. 5 min × 10 emails × 250 working days = 12,500 minutes = ~208 hours of recruiter time saved per year. That is more than 5 full working weeks back, plus a better candidate experience.

Frequently asked questions
+ What is an AI email tool for recruiters?
An AI email tool drafts candidate-facing emails from a prompt and the data your ATS already has on the candidate. The 100Hires AI Email Composer sits in the Messages tab of every candidate profile and reads resume, job description, application answers, email history, evaluation notes, job notes, and interview discussion notes before drafting. The recruiter reviews and sends. It is not autosend - the human stays in the loop.
+ Can AI write my rejection emails?
Yes, and this is the most common reason recruiters turn the 100Hires AI Email Composer on. Save a prompt like "Draft a polite rejection that highlights the candidate's strengths and keeps the door open for future roles." The AI reads the interview discussion notes and writes a rejection that references what the candidate actually said. The reviewer edits if needed, then sends. Candidates who get a personalized rejection are far more likely to apply for future roles than those who receive a 4-line generic template.
+ Are AI email tools worth it for small recruiting teams?
Depends on volume. If you send 5 candidate emails a year, no - generic templates work. If you send 10 a day or hire 50+ people a year, the AI Email Composer pays for itself in saved hours plus higher reply rates. 100Hires test customers report 20-30 minutes saved per personalized rejection, and around 5 minutes per email across the broader mix - that adds up to ~200 hours per year for a recruiter who sends 10 emails a working day.
+ Does the AI Email Composer cost extra?
No. It is included on every paid 100Hires plan, with no per-user, per-email, or per-token surcharge. The AI API costs are absorbed by the platform.
+ Can I create custom AI prompts for my team?
Yes. In 100Hires, go to Settings > AI Prompts and switch to the AI Email Composer tab. Add, edit, or delete saved prompts. The library is shared across your company - one library for the whole team, so the prompts your senior recruiter saves are immediately available to junior recruiters and hiring managers - sorted by recency, and editable any time.
+ What context does the AI use to write the email?
100Hires feeds the AI the resume, application answers, full email history with the candidate, evaluation forms (scorecards), job description, job notes (your internal hiring priorities), and discussion notes (anything the interview panel typed in the candidate profile after each interview). Same data sources as the AI Copilot for screening.
+ Can I transform an existing draft instead of starting from scratch?
Yes. If you have already typed part of the email, three transform actions sit in the 100Hires composer toolbar: Grammar (fix typos and grammar without changing meaning), Rephrase (rework the sentences while keeping the message), and Friendly (warm up the tone for candidates who need a softer email). Useful when you started a draft and want help polishing rather than full generation.
