Writing marketing emails is one of those tasks that takes way longer than it should. Not because it’s hard, exactly, but because staring at a blank screen trying to sound compelling about your Tuesday promotion is a special kind of energy drain.
Artificial intelligence (AI) can fix that specific problem right now, at price points that make sense for small businesses. Here’s how, across three budget tiers.
Free Tier: Use What You’ve Already Got
If you’re not ready to pay for anything new, you can use the free versions of ChatGPT, Claude, or Google Gemini to draft email copy and paste it into whatever email platform you already use.
This isn’t fancy. It’s practical. You tell the AI what you’re promoting, who your audience is, and what tone you want. It gives you a draft in seconds. You edit it, drop it into Mailchimp’s free plan or MailerLite or whatever you’re using, and hit send.
Where this really shines: generating subject line variations. Instead of agonizing over one subject line, ask the AI for ten options and pick the best two for an A/B test. That alone can improve your open rates over time — and it takes under a minute.
**Cost: $0.** If you want longer, higher-quality outputs, paid tiers run around $20/month — ChatGPT Plus and Claude Pro are each $20/month, and Google Gemini Advanced is $19.99/month as part of Google One AI Premium. Verify these prices on the vendors’ sites before you buy, as AI tool pricing can change with little notice.
Mid Tier: Brevo’s Smart Sending
Brevo (formerly Sendinblue) offers AI-powered send-time optimization on its Business plan. Pricing is based on email volume — not contact count — which matters if you have a big list but only send a few times a month. Check brevo.com/pricing for current rates, as Brevo adjusts pricing periodically.
The AI analyzes when each individual subscriber tends to open emails and delivers yours at that optimal window. It’s designed to improve open rates without you touching a spreadsheet or building segments manually. Brevo also includes an AI writing assistant for drafting content.
**One thing to know:** Brevo’s marketing claims significant open rate improvements from send-time optimization, but those are vendor numbers, not independently verified data. The feature is legitimate, but set your expectations based on your own results, not their best-case scenario.
Integrated Tier: Mailchimp’s Intuit Assist
Mailchimp’s Standard plan includes generative AI baked directly into the campaign builder through Intuit Assist. It’ll draft subject lines, body copy, and suggest send times based on subscriber behavior. Check mailchimp.com/pricing for current rates and confirm whether the price shown is for monthly or annual billing — Mailchimp sometimes displays the annual-billing price by default, and the month-to-month cost may be higher.
The workflow looks like this: you input your promotion details, the AI generates three subject line variants and full email copy, you tweak what needs tweaking, and you send. The value isn’t that the AI writes perfect emails — it’s that it kills the blank-page problem and gets you to a sendable draft fast.
**Important:** Mailchimp’s full generative AI features — like AI-drafted body copy and advanced send-time optimization — require the Standard plan or above. The free tier may include limited AI features like basic subject line suggestions, but don’t sign up for free expecting the full AI campaign experience.
What This Actually Saves You
The honest answer: AI doesn’t guarantee better email performance. The independent data on AI-written vs. human-written emails for small businesses specifically is thin. What it reliably saves is *time on first drafts and testing setup.* If your current process involves staring at a blank compose window for 45 minutes every week, that’s real time back.
**Your one takeaway:** Start at $0. Use a free AI tool to draft your next email campaign and generate ten subject line variations. See how it feels. If you want the AI built into your email platform handling send times and drafts in one place, Brevo and Mailchimp both offer reasonable paid plans — verify current pricing on their sites before you commit. Try the free version first, upgrade only when you’ve felt the time savings yourself.
