Email API & Marketing
High-deliverability email with double opt-in, one-click unsubscribe, open/click tracking and A/B testing.
Email remains the backbone of customer communication. WeZend delivers both transactional and marketing email over your own infrastructure or ours, with deliverability guards built in: authentication, double opt-in, one-click unsubscribe, quiet hours and frequency caps. Every open, click and bounce feeds the CDP so you can segment and automate on real engagement.
