AI can speed up campaign planning and first drafts by helping with angles, subject lines, preview text, body copy, and calls to action. Use it as a drafting assistant, not an authority: provide verified inputs, review every claim and link, and check the finished message for brand fit and compliance before sending. No fixed time saving or performance lift is guaranteed.
Where AI fits in an email campaign workflow
AI is most useful for generating and reshaping copy that a marketer can evaluate. It can produce options quickly, but it may misunderstand an offer, invent details, or miss the context that makes a message sound like your brand. Start with approved facts and treat every output as a draft.

HubSpot’s AI email creation documentation, last updated March 31, 2026, describes generating a marketing email for a target audience and action, using an existing layout or template, with a subject line, preview text, body, and calls to action. Access to generative AI tools must be enabled; the documented eligibility is Marketing Hub Professional and Enterprise. HubSpot recommends proofreading, editing for brand voice, balancing AI output with human-written content, and checking accuracy, especially statistics and content not generated in English.

10 practical ways to use AI for email campaigns
1. Brainstorm campaign angles
Give the tool the campaign goal, audience, offer, and constraints. Ask for several genuinely different directions—such as emphasizing convenience, a specific use case, or a deadline—rather than ten near-identical subject lines. Choose an angle that matches the actual offer and your audience’s needs.

2. Generate subject-line options
Ask for alternatives with different tones or value propositions, then check each one against the email itself. A subject line should not imply a discount, deadline, result, or benefit that the message cannot substantiate. A catchy line is not useful if it misleads the recipient.
3. Draft preview text
Request preview-text options that add useful context to the subject line. The preview can explain who the offer is for, clarify a benefit, or introduce the next step; avoid simply repeating the subject in different words.
4. Create a first body-copy draft
Supply verified product details, the intended audience, offer terms, and the message’s purpose. State what the reader should do next and provide any required restrictions or exclusions. Review every factual claim against approved materials before using the draft.

5. Write calls to action
Ask for concise CTA alternatives that describe the reader’s real next step. Match the wording to the landing page or action—such as viewing details or registering—rather than promising an outcome the click does not deliver.
6. Repurpose approved material
Give the tool approved product information, an editorial piece, or other source material and ask for a campaign draft based only on that content. Compare the result with the original: summarization and rewriting can omit conditions or introduce claims that were never approved.
7. Adapt the tone to your brand
Provide a short voice guide and a few representative examples. Specify practical traits—such as formal or conversational, concise or explanatory—and words or claims to avoid. Then edit the result yourself; a prompt can guide style, but it does not ensure that every line will sound like your brand.
8. Personalize carefully
If your email platform supports personalization, use relevant audience or CRM information to tailor copy. Check that the data is accurate, that the recipient belongs in the intended segment, and that the resulting message remains appropriate for that person. Personalization can depend on the platform, subscription, data-sharing settings, and usage limits.
For example, HubSpot’s nurture-agent documentation, last updated September 16, 2026, describes a beta that uses CRM data and web research to tailor subject lines, preview text, CTA text, and body copy for a percentage of recipients. The documented requirements include eligible Marketing Hub Professional or Enterprise subscriptions and HubSpot credits; AI access and data-sharing settings can also be configured. This is a conditional beta, not a universal feature. Read HubSpot’s nurture-agent documentation.
9. Prepare alternatives for review
Use AI to create distinct versions for a marketer to assess—for example, one that leads with a product use case and another that leads with an offer. Decide which is clearer and more suitable for the audience. Do not assume a generated variant will improve opens, clicks, conversions, or revenue without campaign evidence.
10. Build reusable prompts and review checks
Save approved inputs, brand guidance, constraints, and a review checklist for recurring campaigns. A reusable prompt can reduce setup work, while the checklist helps catch errors that a prompt cannot reliably prevent.
How to build a reliable AI-assisted workflow
- Assemble approved inputs. Collect the campaign goal, audience, verified product details, offer terms, destination URL, and brand voice guidance.
- Ask for a specific deliverable. Request the components you need—such as three campaign angles, five subject lines, preview text, a body draft, or CTA options—and state the audience and constraints.
- Compare the output with the source. Remove invented details, unsupported benefits, incorrect restrictions, and wording that could be misunderstood.
- Edit for readers and brand fit. Check whether the message is clear, useful, and consistent with your voice; revise awkward or generic copy.
- Run the pre-send checks. Verify the message, audience, destination, and required commercial-email details before scheduling or sending.
What time-saving claims do—and do not—show
HubSpot’s AI email marketing article reports that 54% of marketers saved 1–5 hours per week and 31% saved 6–10 hours per week through AI in their email workflow. Those figures are attributed to HubSpot research, but the surfaced article does not provide the sample, field dates, or methodology details. Treat them as reported survey results, not a forecast for your team. The time you save will depend on your workflow, the quality of your inputs, and how much review each campaign needs. See HubSpot’s AI email marketing article.

- Facts and offers: Verify names, dates, prices, terms, restrictions, statistics, and product claims against approved sources.
- Links and actions: Test links and confirm that the CTA matches the destination and the action available there.
- Audience: Confirm that targeting and personalization data are accurate and appropriate for the recipients.
- Voice and clarity: Edit for brand voice, plain meaning, and a useful message—not just polished-sounding prose.
- Sending requirements: Check required sender details, advertising identification, opt-out handling, and applicable rules for the markets where you send.
AI does not transfer responsibility for commercial email
In the United States, the FTC says the CAN-SPAM Act applies broadly to commercial messages, including business-to-business email. Its requirements include accurate header information, non-deceptive subject lines, clear and conspicuous identification of advertising, a valid physical postal address, an opt-out mechanism, and honoring opt-out requests within 10 business days. The sender remains responsible even when another company is hired to send the email. Read the FTC’s CAN-SPAM compliance guide.
Advertising identification does not have to appear in the subject line. FTC attorney Christopher E. Brown explains that “The CAN-SPAM Act doesn’t require senders to identify the message as an advertisement in the subject line.” That does not permit a deceptive subject line; the ad identification must instead be clear and conspicuous in the message. See the FTC’s answers to CAN-SPAM questions.
Platform policies can add their own requirements. Mailchimp’s guidance, for example, says contacts must consent to receive marketing email and advises senders to consider audience settings, subscribed contacts, and relevance. Treat that as Mailchimp platform guidance, not a complete statement of U.S. law. Read Mailchimp’s compliance guidance.
Choose AI features based on the job you need done
When evaluating an email platform’s AI capabilities, distinguish copy drafting from recipient-level personalization. Check whether the feature is available on your subscription, whether it uses CRM or audience data, what data-sharing controls apply, whether credits or other usage limits are required, and how it fits your templates and review process.
Intuit announced a Mailchimp email content generator in 2023, describing copy options based on industry, marketing intent, and tone. That announcement establishes the feature’s historical existence, but not its current availability. Verify the present product status before relying on it. Read Intuit’s 2023 announcement.
