## A retainer is a capacity contract

An email marketing agency typically sells a monthly block: strategy call, campaigns, flow edits, reporting. The useful retainers name the outputs (two campaigns, one flow experiment, a QA pass) and the people (senior strategist versus production only). The useless ones sell 'always-on email' with no inventory of what ships.

Rates vary by city and seniority. A specialist boutique can cost as much as a mid-size digital shop's junior pod. Price is not quality. Ask for live ESP access in a walkthrough of an account they still run, with client permission. If they can only show PDFs, you are buying slides.

*The agency can build. The list should stay in an account you control.*

## Who owns the list

You do. Put that in the statement of work. The agency operates the audience. The company that collected the consent owns the records, the unsubscribes, and the suppression. Admin users should include at least two people at your company. Export rights should be explicit: CSV of subscribers, unsubscribes, and campaign HTML.

If the list lives in the agency's master [Mailchimp](https://mailchimp.com) or [Klaviyo](https://www.klaviyo.com) account, you are renting your own customers. Migrating out then means a new sending domain or a painful merge, plus email-aisle reputation that stayed with their domain. Do not allow that structure. Your domain, your ESP subaccount or account.

## How this differs from a 'company' or 'services' search

Agencies are a subset of services: a firm whose identity is the practice, usually with a roster of clients. An ESP's professional-services arm is still the software vendor. A freelancer is one person and no bench. Hire an agency when you need coverage (someone is out) and a process. Hire a freelancer when you need one excellent operator. Hire nobody extra when the bottleneck is the offer, not production.

Creative-only email shops will make beautiful modules that never map to segments. Lifecycle shops will make flows that look like plumbing. You probably need a bit of both. One contract can cover it if they staff both. Many cannot.

## Common questions

**Should the agency's name be in the from-line?**

No. The from-name is your brand or a person at your company. Reply-to should be a mailbox you read. Agencies that send as themselves train the list to ignore you when they leave.

**How long before an agency should show results?**

Flows can move revenue in weeks if the store already has traffic. A cold list and a new domain need a slower ramp (email aisle) before you judge copy. Give a new domain a warmup plan, not a week-one blast to 80,000 addresses.
