The era of 20% email open rates is not the end game. AI enables 'uncomfortably specific' targeting in subject lines and content, which can dramatically boost engagement. This has the potential to bring open rates back towards the highly effective levels seen in email's early days.

SaaStr's AI agent 'QB' composed and sent unique emails to over 80 event sponsors after midnight. It used chatbot data for topic ideas and created a custom checklist of outstanding tasks for each sponsor, then sent them all in minutes while the human team slept.

Generic "we miss you" campaigns fail. Instead of a simple message, leverage integrated data to personalize outreach based on an HCP's past behavior. This "we miss you, and we know you" approach has yielded click-through rates exceeding 40% by offering highly relevant content suggestions.

Combine two specific audience identifiers in your subject line, like role and company attribute ("Mid-market CMOs") or interest and a pain point ("Beauty fans with sensitive skin"). This "double personalization" tactic reportedly increases B2B open rates by 24% and B2C by 29% by making the message feel hyper-relevant.

Modern AI enables hyper-personalization where every email element—copy, images, discounts—is generated uniquely for each shopper based on real-time site behavior. This moves beyond simple segmentation to a one-to-one communication standard.

To achieve personalization efficiently, Samsung creates a few core email templates. They then use third-party tools like Movable Ink to dynamically insert content modules based on individual customer data, such as products owned or purchase propensity. This avoids massive versioning complexity.

Quo's personalized "year in review" campaign visualized customer product usage into shareable stats. This "surprise and delight" tactic, not focused on upsells, generated significant social media buzz by giving customers credible data to showcase their own business success, effectively creating user-generated brand marketing.

Faced with sending a personalized email campaign to a 200,000-person list, the host partnered with Clary, a specialist in mass-scale outreach. This shows the value of leveraging external expertise and technology to execute ambitious projects that would be unfeasible with internal resources alone.

By using AI tools like Apollo to scrape and segment customer lists, the founder sends thousands of personalized emails daily. This automated system for lead generation allows a one-person team to manage a high-volume B2B sales funnel, initiating conversations at scale before adding a personal touch.
