The challenge
An incumbent ESP that couldn't keep up with growth.
Iterable is an all-in-one platform for transactional, promotional, and lifecycle messaging. Its team makes it easy for marketers to create automated, targeted emails and push with modern APIs and integrations that reduce engineering time — a full suite spanning subscriber segmentation, A/B testing, a drip campaign builder, and real-time analytics to maximize revenue and engagement.
- Doubts about scale. Iterable was not confident its incumbent ESP could scale with fast-growing sending volumes.
- Spotty reliability. Performance could be inconsistent, with incidents where emails were delayed or undelivered.
- A search for a new partner. After repeated incidents where emails were not sent out in a timely way, Iterable decided to begin a search for a new cloud email partner.
The solution
A proven email platform, live in about a week.
The Iterable team chose Bird for three reasons.
- Industry reputation.Message Systems' standing as an industry leader, backed by strong recommendations from trusted advisors experienced in high-volume digital messaging.
- Quick onboarding. The transition to Bird was completed in about a week.
- Expertise and support. Prompt responses to technical integration inquiries, plus help formulating strategies for ramping up dedicated IPs for Iterable customers.
“The core of our business is giving marketers intuitive tools to send emails and push notifications in a way that delights users and drives conversion. Bird eliminated the problems we were having to the point where excellent deliverability is now a competitive advantage for us. Our volumes are at an all-time high, and we're confident this can scale even higher as needed.”
Justin Zhu, Co-founder & CEO, Iterable
