Woodpecker $35, Smartlead $39, Salesforge $48, QuickMail $49, HeyReach $79. All published monthly, all self-serve, all verified between 6 and 12 August 2026.
The number that matters is what happens to each of those when you add the eleventh client.
The two things an agency actually needs
Workspace separation, so one client's data, domains and reporting do not touch another's. And sending identities that are not rationed, because each client needs its own domains and mailboxes and a per-mailbox fee turns into the dominant line at scale.
Most tools in this category were priced for a company running its own outbound. An agency is a different shape: many small sending footprints rather than one large one, and pricing built for the first shape punishes the second.
Where the money actually goes
Three separate meters run at once, and pricing pages usually show one:
- The platform fee, which is the number on the page and usually the smallest of the three.
- Mailboxes and domains, billed per identity. At 5 to 15 mailboxes per client this becomes the largest line and it is rarely on the pricing page.
- Data and verification credits, which scale with list size rather than client count and are metered separately again.
One operator reported the shape plainly: a plan at $358 a month, and $1,700 a month for the credits needed to use it. The credits cost nearly five times the seat. That is a reported claim rather than a measurement, and it matches the structure every pricing page in this category publishes.
The question to ask before signing
Not what it costs a month. What it costs per client at the number of clients you expect to have in a year. A $79 tool with unlimited workspaces beats a $39 tool billed per workspace the moment you pass three clients, and both pages advertise the smaller number.
Then ask who owns the domains, and settle it before the first send. If your agency registered them, a departing client cannot take their sending reputation with them. If the vendor registered them, neither can you. Either way that is weeks of warmup nobody gets back, which makes it the cheapest clause to agree at signup and the most expensive to argue about at churn.
