Email still matters. Every day people use email for work, sales, customer support and personal notes. Writing good emails takes time. That is where AI tools help. They can suggest subjects, write drafts, fix tone, and even personalize messages for many people at once. In this blog I will explain how these tools work, the most popular options, simple tips to use them well, and the risks to watch for. I’ll keep the language easy and the ideas practical.
What AI email tools do
AI email tools use language models to read short instructions and then produce text. You tell the tool who the message is for and what you want to say, and it writes a draft. Many tools also check grammar, suggest a different tone, shorten long threads, or create follow-up emails. Some tools plug directly into your mail client, while others work in a web app or browser extension.
AI tools can save time and reduce writer’s block. They are especially helpful when you must write similar messages again and again — for example, sales outreach, onboarding new users, or short customer replies. But these tools are not perfect. They work best when you give clear input and then edit the result before sending.
Popular AI email tools you should know
There are many AI email helpers. Some are made specifically for sales and outreach, while others are part of larger writing suites. Below I describe a few widely used options so you know what they do and when to try them.
Lavender is an AI “email coach” made for salespeople. It scores your email drafts and suggests changes to improve reply rates, personalization, and clarity. Lavender focuses on outreach: helping sales reps write messages that get more responses. (lavender.ai)
Flowrite / MailMaestro started as Flowrite — a tool to turn short prompts into full emails — and now appears under broader brands like MailMaestro in some places. It offers templates and a one-click draft generator so you can create or rewrite emails quickly. If you often need to write different kinds of messages in several languages, this kind of tool is useful. (maestrolabs.com)
Grammarly (now evolving into Superhuman) began as a grammar and clarity checker and added AI draft features for emails. Recently it has been part of bigger moves in the productivity space, combining writing help with tools that integrate into email clients. If you want strong grammar checking plus some drafting help inside your editor, products from this family are worth a look. (Grammarly)
Jasper offers AI writing tools that include email generators. Jasper can produce marketing emails, cold outreach, and follow-ups with prompts and templates. It’s often chosen by marketers and content teams that need consistent tone and fast output. (jasper.ai)
Salesforce Einstein (Einstein GPT) is built into Salesforce and can use your sales data to write personalized emails for leads and customers. Because it accesses CRM data, Einstein can ground messages in facts about the contact, making outreach feel more relevant. This is a strong choice if your team already uses Salesforce. (Salesforce)
These are not the only tools. Many email platforms and marketing tools also add AI features for subject lines, content suggestions, and audience personalization. The field moves fast, so expect new features and new players over time.
How to use AI tools in everyday email work
Start small. Use AI to draft the first version, then edit. For many people this workflow saves time while keeping quality high.
Begin by giving the tool a clear prompt. Tell it the recipient type (boss, client, new customer), the goal (ask for a meeting, give instructions, follow up), and the tone (friendly, formal, urgent). Better prompts give better drafts.
Always check facts and names. If the AI invents details or misstates data, correct those before sending. Treat the AI draft as a smart suggestion, not the final email.
Use AI for repetitive tasks. If you send onboarding emails, thank-you notes, or monthly updates, set up templates and ask the AI to customize them for each recipient. This keeps writing fast and consistent.
If you work with sales or outreach, combine AI with human judgment. AI can create many versions of a cold email quickly, but you must personalize lines that will actually connect with a person. A short, true personal sentence is often the thing that wins replies.
Tips to get better results
Be specific in the prompt. For example, say “Write a short, polite follow-up to remind a client about an invoice due in three days” rather than “write a follow-up.”
Limit length when needed. Ask the AI to keep emails under a set number of words for busy recipients. Short, clear messages usually perform better.
Use a consistent voice. If your company has a brand voice, provide an example sentence and ask the AI to match it. This helps maintain professionalism across many messages.
Check subject lines separately. A good subject line can make a big difference. Try asking the tool for several short subject line options and pick the one that feels most natural.
Keep security in mind. Don’t paste private or sensitive data into third-party tools that do not guarantee data protection. For very sensitive emails, use tools integrated into secure platforms or that offer enterprise privacy controls.
Problems to watch for
AI can introduce errors. It may invent dates, exaggerate achievements, or create wrong statements. Always verify numbers and names.
Tone can be off. AI sometimes writes in a style that sounds stiff, too casual, or generically polite. Edit the draft so it fits your relationship with the recipient.
Privacy and data control matter. Many free or cheap services use your content to improve models. If you handle sensitive customer data or regulatory information, use providers that offer clear privacy terms or an enterprise plan.
Over-reliance reduces skill. If a person always uses AI to write emails, they might lose the practice of writing clear messages themselves. Use AI to help, not to replace learning.
When AI helps the most
AI shines when the task is repetitive, when you need many similar emails, or when you face writer’s block. Marketing teams, customer success, HR, and sales can all benefit.
It also helps with language support. If you must write to people in different languages, AI can create a clear draft that you can then fine-tune for nuance.
For teams that use CRM systems, tools that integrate with the CRM and use real data can produce very effective personalization. That connection between your records and the email content is a major advantage.
Quick workflow example
Imagine you need to send 50 follow-up emails after an event. Use an email AI tool to:
-
Create a base draft with the main points (thank, remind, offer next steps).
-
Ask the AI to produce short variations with slightly different openings.
-
Manually add one line of personalization pulled from your CRM (for example, “It was great to meet you at the design workshop”).
-
Send from your mail merge system and track replies.
This keeps your messages personal enough, but it removes the heavy lifting of writing every full email by hand.
Cost and plans
Many AI email tools offer free tiers with limited features, and paid plans that unlock advanced templates, integrations, and privacy options. If you choose a tool for business use, check for:
-
Integration with your mail client or CRM.
-
Team features for sharing templates.
-
Data privacy and contract terms that meet your company policy.
Final thoughts
AI tools for writing emails are powerful helpers. They speed up work, reduce the time you spend on routine messages, and give you good starting drafts. But the best results come when you combine AI with human judgment. Use AI to create, then edit to verify facts, adjust tone, and add the personal touch that machines still struggle to get right.
If you are new to these tools, try a simple free tool first. Use it for routine tasks and test how much time you save. As your comfort grows, try deeper integrations with your email client or CRM to get more personalization and automation.
AI will not replace good manners and clear thinking in email. It will, however, give you more time to focus on the parts of communication that truly need a human: listening, deciding, and caring about the person on the other end.
