Subject lines. CTAs. Countdown timers. Deliverability. And don’t get us started on Outlook.

There are so many elements of email marketing that constantly change, from email client support to design elements like dark mode. When your head’s down in day-to-day email design or campaign development, it can be hard to know where to find the right answers to your questions about topics like email marketing strategy, analytics, developer tips and tricks, design, and deliverability.
