Freelance designers: $150–$400 per email
The most common entry point, and the easiest to compare on paper. A freelancer will usually quote per email, with the rate moving on complexity, turnaround and whether product photography needs retouching.
What the quote normally excludes is everything around the design: campaign planning, copywriting, building the email in your ESP, and revisions past the second round. At four campaigns a month you are looking at $600–$1,600 before any of that, and availability is one person's calendar.
Agencies: $2,000–$8,000 a month
A retention or creative agency bundles strategy, design, copy and often flow work into a monthly retainer. For brands sending heavily, with complex segmentation and a real calendar, that bundle is genuinely worth it.
The friction is scope and cycle time. Retainers are sized to a set number of campaigns, revisions are capped per cycle, and an extra send in a busy month is a change order. Below roughly eight campaigns a month the per-email cost gets hard to defend.
In-house: $70,000–$95,000 fully loaded
A salaried email designer is the best option once volume is high enough — they learn the brand, they are always available, and marginal campaigns are free.
The real number is not the salary. Add payroll taxes, benefits, software, recruiting and the ramp before they are productive, and one designer is $70,000–$95,000 a year in practice. That is $1,500–$2,000 per campaign at four sends a month, and it goes to zero output the week they are on holiday.
DIY in your ESP: the invoice is zero
Building from a Klaviyo or Mailchimp template has no line item, which is exactly why it gets chosen. The cost shows up elsewhere: three to five hours per campaign for someone whose job is something else, emails that look like the template library, and the weeks where the campaign simply does not go out.
At a marketing coordinator's loaded hourly rate that is $120–$250 of internal time per campaign, and it is the option most likely to quietly stop happening.
What actually moves the price
Volume is the biggest lever — per-email pricing falls fast once you commit to a monthly cadence. After that: how much is included beyond design (copy, planning, ESP build, QA), turnaround, how revisions are counted, and whether someone else owns the calendar or you do.
The useful comparison is not the headline rate. It is total monthly spend divided by campaigns that actually shipped, with your own time priced in.
Where a white-glove service fits
Nexmail sits deliberately between the freelancer and the agency: agency-quality design, copywriting and calendar planning done for you, priced closer to a couple of freelance emails a month.
White-glove plans start at $375 a month and cover up to 15 emails, with unlimited revisions and campaigns delivered production-ready into Klaviyo, Mailchimp, Omnisend, Brevo, Campaign Monitor or Constant Contact. At four campaigns a month that is under $95 a campaign with the planning and copy included.
