SaaS Companies Tips & Best Practices
Use product language users recognise
"Your new dashboard is ready" is more relevant than "Exciting platform updates!" Use the same terminology your users see in the product.
Add urgency for trial and billing emails
"Your trial expires in 3 days — here's what you'll lose" creates genuine urgency without being pushy.
Personalise with usage data
"You scored 12 pieces of content this week" is highly personal and relevant. Usage-based subject lines have 2-3× higher open rates.
