Email marketing pricing: DIY, freelancer, or agency?

MailyScaly team · Updated 2026-05-13 · ~7 min read

"How much does email marketing cost?" — the question most agencies answer with "it depends". True, but useless. In this guide we break the cost into concrete parts: what the platforms cost, what the human work costs across three different routes, and most importantly — how to calculate whether it pays off for you at all.

What the cost is made of: platform + work

An email marketing budget always has two line items. The first is the platform (Omnisend, Klaviyo, MailerLite, etc.), priced by list size: roughly $20–50/month for a small list, rising to $100–300/month and beyond as you grow into tens of thousands of contacts. The second line is the work: strategy, building automations, copy, design, segmentation, testing, analytics. The work is what decides whether the channel drives 5% or 30% of your revenue — and that is exactly where the routes diverge.

Three routes and their real costs

Route #1: do it yourself

Cheapest in money, most expensive in time. The reality we see with clients: a serious channel (automations + 4–8 campaigns per month + analytics) takes 20–40 hours per month. If your hour is worth $30, that is $600–1,200 of "invisible" budget — enough to hire professionals. But at the start, this is the right route: launch at least a welcome series and abandoned cart emails — these two automations can be built over a weekend and then run themselves.

Route #2: freelancer

A good option for specific, well-defined jobs — email template design, campaign builds, copywriting. This kind of work typically costs from a few dozen dollars per email up to a few hundred dollars per month for ongoing help. The weak spot is scope: strategy, segmentation, deliverability care, and A/B testing rarely fit into a freelancer's offer — and those are exactly what separate "we send emails" from "email drives a third of our revenue".

Route #3: agency

Market surveys put agency pricing for full email channel management at roughly $600 to several thousand dollars per month, depending on scope. For that money you should get the full package: an audit, strategy, automation setup and maintenance, regular campaigns with copy and design, segmentation, A/B tests, and deliverability care. The key word is should: scopes differ dramatically, so compare scopes of work, not prices.

How to calculate whether it pays off: the ROI logic

In a healthy e-commerce store, the email channel generates 20–30% of total revenue. Work backwards:

1. Your monthly revenue × 25% = the channel's potential. E.g., $20,000 × 25% = $5,000/month from email.
2. Subtract your current email revenue (if you send nothing, that's ~0–5%, usually from "ghost" order confirmations).
3. The difference is what your email marketing budget is buying. If the gap is $4,000/month and an agency costs $1,000/month, the math is clear. If the gap is $500 — it's not time yet.

That's where the practical threshold we apply ourselves comes from: below ~$10,000/month in revenue, hiring an agency doesn't pay off — an honest agency will tell you so itself and suggest you come back once you've grown.

5 questions to ask an agency before signing

1. What exactly is included in the monthly fee? Number of automations, number of campaigns, copy, design — all in writing.
2. Which metrics will you use to measure success? The right answer is email's share of revenue (%), not "open rates".
3. When will I see the first results? Automations should be working within 2–4 weeks; "results take six months" is a dodge.
4. Who looks after deliverability? SPF, DKIM, DMARC, and domain reputation — without these, everything else is pointless, because the emails simply never reach the inbox.
5. What happens if we cancel the contract? The automations, templates, and account must stay yours — avoid "rented" infrastructure.
