How to Write Emails with Content AI in Sparkforge

By Sparkforge Support Team ·Last reviewed May 3, 2026

Content AI is a built-in writing assistant in the Sparkforge email builder that generates subject lines, body copy, button text, and A/B variants from a short prompt. Enable it in Agency Settings > Company, then drop into any text or button block and click the AI icon.

Content AI lives inside the Sparkforge email builder. Once it is enabled at the agency level, every text block, button, and subject line in the email composer can be drafted from a short prompt. It is metered per word, so usage is paid for as it happens rather than locked behind a flat add-on.

What Content AI Generates

  • Subject lines and subject-line variants for A/B tests
  • Email body sections — promotional, introduction, coupon, newsletter, testimonial, cold outreach, and giveaway formats
  • Button labels and CTA copy
  • Outlines and drop-in paragraphs you can refine inline

Enable Content AI

  1. Open Agency Settings and choose Company.
  2. Toggle Content AI on. It is available across every Sparkforge plan.
  3. To pass cost through to sub-accounts, configure rebilling in the SaaS configurator or under Sub-Accounts > Manage Clients.

Use Content AI in an Email Text Block

  1. Open Marketing > Emails and create or edit a campaign.
  2. Drop a text block onto the canvas, then click the AI icon in the block toolbar.
  3. Enter a prompt that describes the email — audience, offer, and tone.
  4. Pick a length and a variation count, then generate.
  5. Insert the result, then edit the copy directly in the block.

Use Content AI in a Button Block

  1. Add a button to the email and select it.
  2. Click the AI icon next to the button label field.
  3. Describe the action you want the reader to take (book a call, claim 20% off, download a guide).
  4. Pick a variation and apply it to the button.

Use Content AI on the Subject Line

  1. Click the subject-line field at the top of the email.
  2. Click the AI icon to generate options based on the email body and your prompt.
  3. Save several variants if you plan to A/B test.

Pricing

Content AI runs on usage-based per-word billing. There is no per-seat charge, and word usage rolls into the same monthly invoice as the rest of the Sparkforge platform.

Frequently Asked Questions

Which Sparkforge plans include Content AI?
All plans. Content AI is enabled at the agency level and is metered by word usage rather than gated behind a specific tier.
Can I rebill Content AI usage to sub-accounts?
Yes. Configure rebilling in the SaaS configurator or per sub-account under Manage Clients so word charges pass through automatically.
Does Content AI work for subject-line A/B tests?
Yes. Generate several subject-line variants from one prompt and select the ones you want to A/B test in the campaign settings.
Does it write the whole email or just sections?
Both. You can generate full outlines, single sections, button labels, or subject lines and combine them as you build the email.
