Email writing

Email tools put AI where a lot of daily writing happens: the inbox. They draft replies from a short instruction, summarize long threads so you can answer without rereading everything, and help sort what needs attention. Some are full email apps with AI built in. Others plug into Gmail or Outlook and coach you as you write.

Sales teams use the coaching kind most. These tools score a draft for length, clarity and tone, suggest changes, and help personalize outreach. Everyone else tends to want faster replies and less time reading threads, which is what AI-first email clients aim at.

Thread summaries are often the most useful feature for people who are not in sales. A long chain with several people can be reduced to the decision that was made, the open questions and who is waiting on whom. Read the summary, then skim the latest messages before you reply, since summaries can miss a late change of plan.

3 AI writing tools in email writing

Lavender

Email coach for sales teams that scores drafts and suggests edits inside Gmail and Outlook.

  • Free plan or free tier
  • Browser extension

Shortwave

  • Free plan or free tier

Superhuman

Fast email app for Gmail and Outlook accounts with AI drafting, thread summaries and inbox sorting.

Short instructions work best for drafting replies. Something like "accept the meeting, propose Thursday instead, keep it brief" usually produces a usable draft. Asking the tool to write a whole message from nothing tends to produce something longer and stiffer than you would send yourself.

Email is personal and often confidential, so access matters. These tools need permission to read your mailbox. Check what the vendor stores, whether it trains models on your mail, and whether your company allows connecting work email to outside apps. And read every AI draft before sending: a wrong date, a promise you did not mean to make or the wrong tone with a client costs more than the time saved.

Questions about email writing

Do AI email tools work with Gmail and Outlook?

Most do. Superhuman works with Gmail and Outlook accounts, Lavender works inside Gmail and Outlook, and Shortwave works with Gmail accounts. Check the tool page and the vendor's site for the account types it supports.

Is it safe to give an AI tool access to my email?

Read the vendor's data terms and your company's IT policy first. These tools read your messages to work, so look for clear statements on storage, model training and security, and use the minimum access they need.

Can AI write my sales emails?

It can draft them and suggest improvements. Personal details, real reasons for reaching out and accurate claims still come from you. Sending generic AI emails at volume tends to hurt replies and your sender reputation.

Will people know my email was written with AI?

Sometimes, when the draft is generic. Editing the draft into your own words, cutting stock phrases and adding a specific detail about the reader keeps emails sounding like you.
