Best Cold Email Software for Agencies: Real Per-Client Pricing

For most agencies the best cold email software is the one with the cheapest client workspace, not the one with the best sequence builder. Saleshandy is the outlier: unlimited clients and white-label at no extra charge, so ten client accounts cost $149 a month on Scale. Smartlead charges $29 per client workspace on top of the plan, QuickMail's Agency plan includes only two workspaces and bills $49 for each one after that, and Woodpecker's Agency Panel is $27 per active client. Same ten clients, and the bill swings from $149 to $691 before a single email goes out. Every price below was read from the vendor's own pricing page in September 2026.

What ten client accounts actually cost

This is the table the general roundups never build, because they compare tools for one company rather than for an agency running many. The figures assume annual billing where it is offered, and cover the software only.

Tool	Base plan (annual)	Per-client charge	10 clients per month	White-label
Saleshandy	Scale $149	None, unlimited clients	$149	Included
AutoMail	Agency $249	None, flat per workspace	$249	Included
Woodpecker	Usage, $7 per 100 contacted prospects	Agency Panel $27 per active client	$270 plus sending	Not published
Smartlead	Unlimited Smart $144.50	Client workspace add-on $29	$434.50	$29 add-on, included on Prime
QuickMail	Agency $299 (2 workspaces)	$49 per extra workspace	$691	Not published
Instantly	Lightspeed $286.30	No published client workspace fee	$286.30	Not published
Lemlist	Email $55 flat	No published client workspace fee	$55 plus seats	Not published

Read that column on the right before the feature list. A five times price gap between the cheapest and the most expensive way to hold ten clients is a bigger number than anything a sequence builder will win or lose you, and it compounds every month for as long as the retainer runs.

Why the usual "best cold email software" lists mislead agencies

Search for cold email software and you get the same eight or nine tools ranked on deliverability, personalization and reporting. Those rankings are written for a company sending on its own behalf, where there is one domain estate, one team and one set of numbers. An agency has none of those things. It has ten domain estates, ten sets of numbers that must not leak into each other, and a client who wants to log in and see their own campaign without seeing anyone else's.

That changes which line on the pricing page matters. Deliverability features are close to table stakes now: unlimited connected mailboxes, warm-up and inbox rotation appear on almost every tool in the table above. What is not standardized, at all, is how the vendor charges you to hold a client. Some treat client workspaces as core architecture and give them away. Some treat them as a margin lever. The tools that give them away are usually the ones that decided years ago that agencies were their market.

The three costs that scale with your client count

Client workspaces. The one above. It is the single biggest variable and the least discussed.

Seats. Agencies add account managers faster than they add clients, and per-seat pricing punishes that. Saleshandy Scale and QuickMail include unlimited users on every plan, Woodpecker includes unlimited team members, and Lemlist's Multichannel tier is $109 per user, which is where a four person team quietly becomes a $436 line item. Check whether the meter is on people or on volume before you sign, because you can forecast volume and you cannot forecast headcount.

Mailboxes and domains. Nearly every tool says unlimited email accounts, and nearly every agency then discovers that the accounts themselves are a separate purchase. Saleshandy's own sending infrastructure is $2.99 per mailbox a month on annual fixed billing, $3.49 on annual flex and $3.99 quarterly, plus $14 a year per domain. Woodpecker sells Google and Microsoft addresses at $6 a month each, other providers at $4, warm-ups at $5 per account and domains at roughly $1 a month on annual billing. Run three mailboxes on each of two domains per client, which is a normal setup, and ten clients means sixty mailboxes. At $3 each that is $180 a month, more than the Saleshandy subscription it sits on top of. Size this before you quote a retainer, and if you are still deciding the ratio, our guide to how many mailboxes per domain is a good place to start.

Saleshandy: the cheapest way to hold a lot of clients

Saleshandy publishes three tiers. Starter is $41 a month billed monthly or $34 annually, with 6,000 emails, 2,000 active prospects and 1,500 lead finder credits. Pro is $99 monthly or $76 annually, with 100,000 emails, 30,000 prospects, 10 users and 4,000 credits. Scale is $189 monthly or $149 annually, with 200,000 emails, unlimited prospects, unlimited users and 8,000 credits. Email accounts are unlimited on every tier.

The agency-specific part is that clients are not metered. Saleshandy's agency offering puts every client in one dashboard, supports unlimited clients at no additional cost, and includes a white-label experience with your logo, colors and a custom domain such as outreach.youragency.com. There is a unified inbox across client accounts and automatic sender rotation. For an agency past about four clients, no other tool in this comparison gets close on cost, and the gap widens with every client you add. The full tier detail is in our Saleshandy pricing breakdown.

The honest caveat is that unlimited clients on one login is a shared-blast-radius design. One misconfigured domain hurting your sending reputation is a problem you now own across the roster, which is exactly the argument for the tools below that isolate clients more firmly.

Smartlead: the most agency-native architecture, at $29 a client

Smartlead was built around multi-client management and it shows. Base is $39 a month, $32.50 annually. Pro is $94, $78.30 annually, with 30,000 active leads and 90,000 emails. Unlimited Smart is $174, $144.50 annually, with unlimited leads and 150,000 emails. Unlimited Prime is $379, $314.60 annually, with 500,000 emails. Email accounts are unlimited throughout.

Client workspaces arrive as a $29 a month add-on per client from Pro upward, and white-label is included on Unlimited Prime rather than charged separately. Each client gets a genuinely separate workspace with its own campaigns and its own reporting, and you get a consolidated view across all of them. That separation is worth paying for when clients are large enough to demand it, or when one of them asks a security question about who can see their prospect list. At ten clients you are looking at $434.50 a month against Saleshandy's $149, so the question is simply whether isolation and the reporting layer are worth roughly $285 a month to you. Our Smartlead pricing guide has the tier-by-tier detail.

QuickMail: unlimited seats, expensive workspaces

QuickMail is $49 a month for Starter with 5,000 emails and 1,000 uploaded contacts, $99 for Growth with 100,000 emails and 25,000 contacts, and $299 for the Agency plan with 500,000 emails and 100,000 contacts. Unlimited email senders and unlimited users on every plan, which is genuinely generous, and no annual discount is published.

The catch is the one agencies hit in month two. The Agency plan includes two workspaces. Each additional one is $49 a month. Three clients is $397, ten clients is $691, and there is no volume break on the way up. QuickMail is a strong product for an agency with a small number of large clients, where 500,000 sends a month matter more than the workspace count. For an agency with many small retainers it is the most expensive option in this table by a wide margin.

Woodpecker: pay for what you send, plus $27 a client

Woodpecker prices on contacted prospects rather than tiers: $7 per 100 contacted prospects a month, with 25 percent off on annual billing, unlimited email accounts and unlimited team members. Add-ons are where the agency bill forms. The Agency Panel is $27 a month per active client, LinkedIn outreach is $29 per connected account, warm-ups are $5 per email account, Google or Microsoft addresses are $6 each and other providers $4, and a dedicated server is $59. The trial is 14 days with no card.

Usage pricing suits agencies with lumpy campaigns. If a client pauses for two months you stop paying for their sending, which no tiered plan lets you do. Model it honestly though: at ten active clients the panel alone is $270 before a single prospect is contacted, and the per-mailbox add-ons stack quickly on top.

Instantly and Lemlist: strong tools, no client-workspace story

Instantly's outreach plans are $47 a month for Growth, $97 for Hypergrowth and $358 for Lightspeed, discounted about 20 percent on annual billing to $37.60, $77.60 and $286.30, with unlimited mailboxes throughout. There is a $555 plan ($500 annually) that carries 500,000 emails and dedicated sending infrastructure, and it is worth understanding what that is: a volume and infrastructure plan, not a client-workspace plan. The pricing page does not publish client sub-accounts or white-label. Plenty of agencies run Instantly anyway and simply keep one workspace per client on separate subscriptions, which works and is not cheap.

Lemlist is $69 a month for the Email plan, $55 annually, billed flat rather than per seat, with Multichannel at $109 per user. The flat email tier is unusually good value for a small agency running a handful of clients, and the per-user multichannel tier is the one to model carefully before you add account managers. Like Instantly, it does not publish a client workspace fee because it does not publish client workspaces.

What white-label actually buys you

White-label means your client logs into outreach.youragency.com, sees your logo and your colors, and never learns which vendor you resell. Saleshandy includes it, Smartlead includes it on Unlimited Prime and sells it as part of the $29 client add-on below that, and the others do not publish it.

Whether it is worth paying for depends on your positioning rather than your client count. If you sell outbound as a managed service and the software is an implementation detail, white-label protects the relationship. If you sell strategy and copy, and the client already knows you run their campaigns in Smartlead, paying extra to hide the logo buys you very little. Be honest about which agency you are before you upgrade a tier for it.

How much does cold email software cost for an agency?

Between $149 and $691 a month for ten clients on the software alone, depending entirely on how the vendor charges for client workspaces. Add mailboxes at roughly $3 to $6 each per month and domains at $14 a year, and a ten client agency running sixty mailboxes lands somewhere near $330 to $900 a month all in. That is your floor cost per retainer before any labor, and it is the number to build your pricing on. We break down the wider economics in our guide to cold email agency cost.

Which cold email software is best for agencies?

Saleshandy for most, on cost. Unlimited clients and white-label at no extra charge is a structural advantage rather than a discount, and at $149 a month on Scale it is a third of what Smartlead costs at the same client count. Choose Smartlead instead when clients are large enough that genuinely isolated workspaces and per-client reporting are part of what you are selling. Choose QuickMail when you have a few big clients and volume matters more than workspace count, and Woodpecker when campaigns start and stop and you want to pay only for months a client is active.

Do agencies need white-label cold email software?

No, and most do not use it. White-label matters when your contract positions outbound as a managed service delivered under your brand, and when a client seeing a third-party logo would raise questions about what they are paying you for. If your value is the strategy, the list and the copy, clients generally do not care which sending platform sits underneath, and you should not pay a tier upgrade to hide it. Where it does earn its keep is in reporting, because a branded client dashboard makes the monthly review feel like your product.

Can I use one cold email account for multiple clients?

Technically yes on most tools, and it is a bad idea past two or three. Sharing one workspace means shared reporting, shared prospect lists and shared sending reputation, so one client's aggressive campaign can damage another client's inbox placement. It also makes offboarding painful, because separating one client's data out of a shared workspace is manual work you will do under time pressure. If your tool charges for workspaces, treat that charge as the cost of not having that problem.

How do agencies report cold email results to clients?

Most send a monthly summary covering emails sent, reply rate, positive reply rate and meetings booked, with the last two doing nearly all the persuading. Open rate is worth reporting cautiously because Apple Mail Privacy Protection and corporate security scanners inflate it, and a client who anchors on a 60 percent open rate will not understand why meetings did not follow. Smartlead and Saleshandy both offer per-client dashboards; many agencies also pull those numbers next to the client's paid and organic channels in one dashboard so the outbound line is read in context rather than in isolation.

Where AutoMail fits

AutoMail is $49 a month on Starter, $99 on Growth and $249 on Agency, flat per workspace with unlimited seats on every plan, so account managers are free and clients are not metered. The difference from the tools above is what it does rather than what it charges: the AI researches each prospect, writes the full personalized opener and the follow-ups, warms and rotates the sending inboxes, then pauses the sequence on reply and routes meeting-ready answers to your booking link.

For an agency the relevant part is where the labor goes. The platforms in this comparison all assume a human writes the sequence, which is fine at three clients and becomes the constraint at fifteen, because copy quality is what your retainer is actually selling.
