The Three Email Marketing Use Cases
Email marketing encompasses distinct workflows with different tool requirements. Marketing newsletters and campaigns (mass email to subscribers) need strong AI copywriting for subject lines and body copy, integrated with email service providers like Klaviyo or Mailchimp. Cold outreach (prospecting new contacts) needs personalization at scale and deliverability infrastructure. Sales email (SDR sequences) needs real-time coaching like Lavender provides.
