What to look for in ecommerce email marketing agencies
Email agencies plan, design, write and send your campaigns and automated flows. For online stores, flows usually earn the steadiest revenue, so a strong agency audits and rebuilds them before scaling campaigns. Therefore, ask to see the flow structure they would set up for you.
Next, check deliverability practices: sender authentication, list hygiene, engagement-based sending and warm-up plans. In addition, look at their creative, since brand voice and design shape how subscribers respond.
Questions to ask on the first call
First, ask which platforms they work in most. Next, ask how they segment lists and test offers. Then ask who writes and designs each email. Finally, ask for results from a store at your size, such as revenue per recipient over six months. As a result, you can compare every candidate on equal terms.
Pricing models to compare
Agencies typically charge a monthly retainer tied to the number of campaigns and flows, sometimes with SMS included. So compare deliverables per month, and confirm that templates and data stay in your account. Above all, get every fee in writing.
