How to Price Email Verification Into an Agency Retainer

Price verification as a part of the deliverable, not a hidden cost. Your cost is a share of one plan, so work out each client's share from usage, then choose how to show it: bundled in the retainer, as a line item, or in tiers by list volume. All three work. The one that fails is absorbing it silently and never mentioning it.

Step 1: know your cost per client

On the Agency plan ($249 a month, 750,000 checks a month at full speed), the cost is a fixed plan, not a bill per list. To split it fairly, use per-client usage by month: lists, rows checked, and the valid, risky and invalid counts, exportable as CSV. Divide each client's rows by the total and apply that to the plan cost. Our post on how many client lists fit in 750,000 checks helps you plan the total.

Do this for a few months before setting prices. Real usage beats a guess.

Step 2: pick a model

Model	How it works	Best when
Bundled	Verification is part of the retainer; no separate line	Clients buy outcomes, lists are similar in size
Line item	A fixed fee per month or per list for verification	Clients ask what they pay for, or list sizes vary widely
Tiered	Included up to a size, then a fee above it	A few clients send far more than the rest

Step 3: write it into the scope

Put these in the contract or SOW:

• Every list is verified before any send.
• Lists are verified again before each campaign, per your re-verification SOP.
• Invalid addresses are not sent; risky addresses are handled per an agreed plan.
• If the client supplies the list, the result split is reported and the client approves what is sent.

Step 4: show it every month

Bundled work gets cancelled first because nobody sees it. A monthly report shows lists verified and the valid, risky and invalid split. See the monthly list hygiene report template and the branded client reports on the Agency page.

What to avoid

• Quoting a per-address price to clients without checking your own usage first.
• Promising a bounce rate. The honest promise is that you check every address before sending.
• Telling clients verification is "free". It is a cost you have decided to cover.

Margin check

If verification sits in the retainer, the plan cost is a small share of what one client pays you. If one client's lists are far larger than the rest, tier them. For the wider margin picture, see cold email agency margin.
