3. Subject Line
This job is about creating Curiosity & Relevance:
People want to know – what’s inside? What’s in it for me?
Describe the contents of your message accurately, and avoid false expectations or complaints.
Do: Optimize for mobile – use 5-8 words.
Draw inspiration for powerful lines from apps like Hemingway, and the Emotional Marketing Value Headline Analyzer.
Don’t: Avoid ‘spammy’ words, symbols, ALL CAPS.
Don’t use 1st name of subscribers.
Relevancy is key to delivering e-mail to the inbox: send the right person the right message at the right time. Segmenting subscribers lets you send the relevant offers and triggers.
Do: Segment by Engagement: Inactive, VIP, New, Cart Abandonment, etc.
Don’t: Settle for just Geographic / Demographic segmentation, look at behavior, too.
Do: Make sure your delivery provider utilizes Sender Policy Framework (SPF) and Domain Keys Identified Mail (DKIM).
Don’t: Get penalized for inconsistency of “From” name.
Trust is worth much more than traffic.
Subscribers who know and trust you, will open your emails, and won’t hesitate to click or share what you offer.
Do: Include your full name & title, and full contact information in your message.
Don’t: Don't send your campaign from a no-reply address. Make it possible to reply directly to you.
