Email marketing agencies are retained for three jobs that look like one: growing the list, sending the campaigns, and building the automations that run without anyone pressing send. The business hiring one should brief all three separately, because the hours and the skills differ, and should keep two things in its own name whatever the agency proposes: the list and the sending platform. The U.S. Bureau of Labor Statistics, cited below, puts the median pay for market research analysts and marketing specialists at $78,760 in May 2025, which is the hire the retainer is measured against; the free worksheet on this site puts the agency's fee beside that hire on the hours the programme actually needs.
Brief the three jobs separately
List growth is a design and acquisition job, campaign sends are a writing and scheduling job, and automation is a build job done once and maintained. An agency proposal that quotes one monthly figure for all three hides which one you are paying for. The brief asks for hours per job so the proposals can be compared on the worksheet per hour rather than on the headline.
Own the list and the platform
The subscriber list and the sending platform account belong to the business, with the agency as a user. An agency that hosts your list on its own account has built the exit cost into the retainer, and the day you leave is the day your list goes quiet. Score it on the card and write it into the retainer record.
Compare the fee with a hire on the hours
Eighty hours a month of email work against a $6,000 retainer is about $78 an hour on the worksheet's defaults, and the specialist hire at the published median is about $121 an hour at those hours but far less at a hundred and forty. The worksheet prints both so the decision follows the hours, and Retainvia Pro keeps the comparison beside the brief.
Questions people ask about email marketing agencies
What should the brief to an email marketing agency contain?
The hours of work a month, the channels, the goal in your own definition, the reporting you will read, the exit terms, and the sector context. One brief to every agency on the shortlist, so the proposals line up on one scorecard.
What should an email marketing agency cost?
The management fee for the hours the brief asks for, compared on the worksheet with the loaded cost of a hire; any media spend is your money and sits outside the fee.
Does Retainvia find the agency for me?
No. It keeps the brief, the shortlist and a scorecard per agency, with the retainer record of what was agreed and delivered; the finding is the business's.
