Use contact data for personalization (e.g., names or recent interaction) and segment subject lines to cater for different groups based on behavior, preferences or demographics thus ensuring relevance and engagement.

Craft clear and concise subject lines (ideally under 50 characters) and communicate the email's value proposition effectively. This includes highlighting special offers, unique content or critical benefits to prompt the recipient's interest.

Apply tactics like urgency (e.g., "limited time offer") and scarcity (e.g., "few items left"), along with elements arousing curiosity, to drive engagement. Use these strategies judiciously to maintain credibility and avoid triggering skepticism or spam filters.

Maintain consistency with your brand’s voice and messaging across subject lines. Regularly A/B test elements for optimization, observing which variations resonate best with the audience.

Tip:

Set a clear goal and include the character or word limit.

Example:

Generate a concise, 40-character long email subject line and inject a universally recognizable emoji for visual appeal.

Tip:

Provide context about the campaign, your brand and the target audience.

Example:

Create a playful yet urgent flash sale campaign for our brand, targeting parents of young children.

Tip:

Specify the desired tone of voice along with the emotional approach and stylistic preferences that are essential for your brand alignment and audience engagement.

Examples:

• The tone should be playful and engaging, using straightforward language.
• The subject line must be engaging, using language that speaks directly to the fun of playing games produced by your brand.

Tip:

Outline the things you would like to include and the ones to avoid.

Examples:

• Avoid common filler words and include an emoji that is universally understandable.
• Exclude common filler words to maximize impact within the character limit.

Tip:

Mention all the desired emotional triggers or appeals.

Examples:

• ​​The subject line should evoke a sense of urgency without being overly aggressive.
• Your role is to spark joy and a sense of urgency, encouraging opening your message instantly without pressure. Emphasize the flash sale's limited time to create urgency.

Tip:

Request different versions for A/B testing or audience segmentation.

Example:

Provide two variations to test: one using a direct call to action and another that is creative and uses an unexpected approach.
