Agency, in-house or both
Should I hire an email marketing agency or build the team in-house?
In-house wins on brand knowledge and on small changes made quickly. An agency wins on range: deliverability, copy, design, build and reporting are five different skills, and one hire rarely covers all five. Most people do best with an agency until the programme is stable, then a hybrid.
How much does an email marketing agency cost?
We won't print a number here: the ranges are so wide it would mislead you. The shape matters more. A one-off build cost agreed in writing, then a monthly retainer for the campaigns and the reporting. Ask what's included, what counts as extra, and what the notice period is.
How long before an email programme shows results?
Flows you already have often improve inside the first month. A rebuilt evergreen stack takes about a quarter before it's worth judging, because enough traffic has to see it first.
Checking what you're told
How do I know the results an agency shows me are real?
Ask which attribution window every figure uses. Ask for the dates. Then ask what the store turned over in the same period, because a revenue share only means something with the denominator attached. And ask to see a programme that didn't go to plan. Everybody has one.
What are the red flags when hiring an email marketing agency?
A figure guaranteed before anybody's opened the account. The platform account held in the agency's name. Reports with no window and no dates, a year committed before the work is proven, a pitch team you never meet again, and deliverability treated as a checkbox.
What should I ask for in writing before I sign?
Scope, the notice period, who owns the platform account and the data, who does the work, and what the reporting looks like and when it lands. An answer that's comfortable on a call is comfortable to write down.
Asking us the same questions
Do I have to move to Klaviyo to work with you?
No. We're an official Klaviyo partner and it's what we build in, so our playbooks assume it. On another platform we'll tell you straight whether moving is worth it, or whether what you've got is fine.
Can I use this guide to score you?
Please do, and do it before the call, not after the invoice. The account and the data stay yours. The flows get built in your platform, the case studies name the client and the period, the team page names who'd run your account, and the terms are thirty-day rolling.
