Use Jasper to Build Brand-Consistent Email Campaigns at Scale

Brand Voice is what makes Jasper different from a generic ChatGPT prompt: it learns your specific voice rather than using a generic tone.

1. Log into jasper.ai → click Brand Voice in the left sidebar (under Campaigns)
2. Click + Add Brand Voice
3. Name it: "[Brand Name] Email Voice"
4. In the Style input section, paste 3-5 examples of your best on-brand email copy (at least 1,000 words total)

• Pick examples that represent your ideal voice: promotional emails, nurture emails, customer-facing communications

1. Add your brand details:

• Brand name: [your brand]
• Products/services: [brief description]
• Target audience: [describe]
• Tone: Select from dropdowns + add custom notes

1. Add specific guidelines in the Custom instructions field:

   - Never start an email with "We" — always start with the reader's perspective
   - Use contractions ("you'll" not "you will")
   - Never use the phrase "amazing" or "incredible"
   - Subject lines: under 50 characters, never include the word "just"
   - CTAs: specific action + benefit ("Shop the Sale" not "Click Here")

1. Click Analyze. Jasper analyzes your examples and builds a voice profile
2. Review the generated voice summary and edit anything that doesn't match

What you should see: A voice summary like "Conversational and direct. Avoids corporate language. Speaks to readers as peers, not prospects. Short sentences. Strong CTAs with specific benefits."

1. Click Create content → Email
2. Select template: Email Subject Lines (for subject-line first approach) or Marketing Email (for full email)
3. Ensure your Brand Voice is selected in the top dropdown
4. Fill in the campaign brief:

• Product/service: [what you're promoting]
• Audience: [who's receiving this]
• CTA: [what you want them to do]
• Key benefit or offer: [the main hook]
• Tone adjustments for this campaign: [any deviation from standard voice, e.g., "more urgent than usual"]

1. Click Generate. Jasper produces 3-5 variations

What you should see: Email copy that sounds recognizably like your brand. If the first generation doesn't nail it, click Rephrase or add more specific instructions in the prompt field.

For a full campaign sequence (welcome series, abandoned cart, etc.):

1. Click Campaigns in the left sidebar → + New Campaign
2. Name the campaign and add your brief (same info as Step 2 plus timing/sequence notes)
3. For each email in the sequence:

• Add an email brief that describes this specific email's goal and how it fits the sequence
• Generate
• Jasper maintains context from earlier emails in the sequence, so it won't repeat the same selling point in every email

1. Review the full sequence as a unit, checking for:

• Tone consistency across all emails
• No repeated phrases between emails
• Logical progression (each email adds something new)

For A/B testing at scale (when you want 10-15 subject line variants to test over multiple campaigns):

1. Open Jasper Chat (more conversational than the template editor)
2. Ensure Brand Voice is active (select it from the dropdown in chat)
3. Paste your prompt:

   Generate 12 subject line options for our [campaign type].
   Topic: [describe]
   Create 3 lines for each of these angles: urgency, curiosity, benefit-first, personalization.
   Each line should be under 50 characters.
   Brand voice is [your brand name].

1. From the 12, run 2-3 A/B tests over multiple campaigns
2. Track which angles consistently outperform. After 6 months, you'll know your audience's preferences with data.
