Summarize this documentation using AI
Email is supposed to be the channel that prints predictable revenue. But in most teams, it turns into a last-minute newsletter, a few promos, and a welcome email that never gets improved.
The real gap usually looks like this: lifecycle flows are missing, segmentation is shallow, testing rarely happens, and performance reporting focuses on opens instead of revenue.
This guide explains what an email marketing agency actually does, what services you should expect, how pricing works, and how to choose the right partner for your stage and goals.
