AI email writer: how it works and how to set it up

The AI email writer on the levelpartner.ai platform drafts emails inside the tools that send them: the email builder for campaigns and templates, and the Send Email action inside a workflow. You give it a context, a short description of the email and a tone, and it returns drafts you edit and send from your own domain. This article covers how to set it up, how to brief it so the drafts sound like your firm, and which emails a person should still write from scratch.

What an AI email writer is good at, and what it cannot know

Any AI for email writing is quick at structure. Hand it an audience, a single goal and the facts that matter, and it comes back with an opening, a body and a call to action in a sensible order. It is also useful for variations: a shorter version, a different tone, several subject lines to test against each other.

It cannot know what sits outside the brief. It has not met the client, does not know the deal stalled last spring and has no idea your firm never discounts. When a gap appears, it fills it with something plausible, and a plausible invention in a sales email costs more than a blank line, because the reader who spots it stops trusting everything around it.

That split decides how you use it. The tool writes the scaffolding; the person who knows the relationship supplies the substance and the final read.

Why the writer belongs inside the platform

Plenty of people use a mail AI writer in a browser tab: type a prompt, copy the result, paste it into their email tool, fix the formatting. Every round trip loses context and leaves the draft sitting in someone's browser history rather than in your records.

On the platform, the draft is created where the email is built. It goes straight into a campaign, a template or a workflow step, sends from your authenticated domain, lands on the contact's timeline and counts in your reporting. Client details stay in the same system as the contact record instead of being pasted into an outside website.

Before you start

• Email sending set up, with your sending domain authenticated.
• A voice note of five or six rules your team can paste into every brief: how you address readers, sentence length, words you never use, how you sign off.
• Three or four of your best past emails, to show what good looks like.
• A named reviewer for every AI-drafted email that will go into a workflow or to a list.
• A written rule on what drafts must never state: prices you have not approved, guarantees, legal or financial advice.

How to set up the AI email writer

There are two places to draft. The email builder suits campaigns and templates. The workflow action suits emails that send automatically when a contact reaches a step.

Drafting in the email builder

1. Go to Marketing > Emails > Email Campaigns and click Create Campaign.
2. In the Email Builder, drag in or edit a Text Block.
3. Click the Content AI button above the text editor.
4. Choose a context from the Select Context dropdown.
5. Enter a Content Title and a short Content Description.
6. Select a Writing tone and the Number of Variations.
7. Click Generate.
8. Click Copy next to the variation you want, then Continue.

For a reusable format, start from Marketing > Emails > Templates and choose New instead of a campaign. The subject line has its own Content AI option on the send and schedule screen, with the same description, tone and variation choices.

Drafting inside a workflow

1. Click Automation, then select Workflows.
2. Click + Create Workflow, or open an existing workflow.
3. Add a trigger, then click + to add an action.
4. Select Send Email from the Communications section.
5. Name the action and enter the From Name and From Email.
6. Click Write with AI in the Message section.
7. Choose a Tone and enter a Prompt describing the email.
8. Click Generate Email.
9. Review and edit the subject and body, then click Use Email.
10. Optionally send a Test Email, then click Save Action.

Writing the brief that decides the quality

Treat the writer as an email writer bot that follows instructions literally. The difference between a usable draft and a generic one is almost all in the description you give it. "Write a follow-up email" produces the message every competitor sends. A strong brief names who the email is for, what happened before, the one action you want and what to avoid.

Your voice note does more work than any single brief. Describe behaviour, not adjectives. "Professional and friendly" tells the model nothing; "second person, short sentences, no exclamation marks, never say reach out, name the reader's problem first" produces drafts you recognise as yours. Add one paragraph you consider on-voice, because models copy examples more reliably than they follow descriptions.

Professional emails, cold emails and sequences

Replies and follow-ups to people who already know you are where the writer needs least correction: proposal follow-ups, meeting recaps, document requests. The reader expects to hear from you and the shape is predictable, so only the details change.

Cold outreach is a different job. Unsolicited email needs a specific reason to write and one clear request, and AI drafts drift towards polite generalities that get ignored. If you use it here, put the trigger in the brief (a new office, a hiring post, a rule change), keep the list small and researched, and delete the first sentence of whatever comes back. Check the consent rules for unsolicited email in every country you send to; they differ between the United States, the United Kingdom and elsewhere.

For a sequence, plan before you generate. Write one line per email stating its job, then draft each one separately so every message has a reason to exist. Someone still has to decide that the series is five emails, aimed at this audience, with this goal.

Guardrails before anything sends

Set three rules and keep them. First, no AI draft enters a live workflow without a human read, because a workflow repeats the same email to every contact who reaches that step. Second, the brief holds every fact the email may state, so the reviewer's job is simple: anything not in the brief comes out. Third, regulated content gets the same compliance check it always had; mortgage brokers in particular should treat a drafted email like any other financial promotion.

Weekly time and what it replaces

The voice note and your first three templates take about two hours to set up. After that, the writer saves time on every email rather than costing time. Budget a careful review for each workflow email, because it will send many times, and spend a short session each month checking which AI-assisted templates get replies and retiring the ones that do not.

It replaces the blank page and the habit of reusing last month's email with the old date still in it. It does not replace the person who knows what the email has to achieve. For longer pieces, the AI blog writer covers articles, and AI writing covers drafting across the platform.

When not to use it

Write these yourself: complaints, bad news, apologies, anything about money owed, contract terms and emails in a dispute. Do not let a drafted email pretend to be a personal one-to-one note when it is a bulk send. And keep the first message to a very important prospect in your own words, because the personal touch is the point.

Troubleshooting

Every draft sounds the same. The description is too thin or you reuse one brief for everything. Add the specific audience, one fact only you know and an example paragraph, and vary the angle per email.

Drafts invent figures or names. The writer is filling gaps. Add a line to the voice note telling it to use only facts in the brief, then check every number, date and claim anyway.

Merge fields turn into plain text. Editing a variation can overwrite a field. Reinsert first name and other fields, set a fallback such as "there" for missing names, and send a test.

Emails land in spam. That is a sending issue, not a writing one. Check domain authentication and list quality, and keep links and images modest.

Frequently asked questions

Can the AI email writer send emails on its own?

The writer drafts and a person approves. Once you approve a workflow email, it sends automatically to each contact who reaches that step without further AI involvement. Automatic replies to incoming messages are a job for an AI agent, covered in AI follow up.

Is a mail AI writer the same as an AI email assistant?

They overlap. A writer drafts emails; an assistant may also sort an inbox or schedule meetings. On the platform, drafting sits in the email builder and the workflow email action, and sending stays under your control. For the SMS equivalent, see AI text messaging.

Is AI writing for emails billed separately?

AI content is billed at cost as you use it, alongside your email sending. There is no separate subscription for the writer, and your licence covers the feature itself.

Will recipients know an email was written with AI?

Not if you edit it. Unedited drafts have a recognisable rhythm and stock phrases. A specific detail, a real example and your own signature remove that, and the AI content writer guide covers the same editing habit for other formats.
