FOR AGENCIES

Best cold email platforms
for agencies

Six platforms, assessed on what actually matters for running client accounts: deliverability infrastructure, pricing that doesn't punish adding a client, real multi-client workspace features, and how much setup work each one demands. ForgeSend is one of the six under review here — not the assumed winner.

METHODOLOGY

How these were evaluated

Every pricing figure and feature claim below was pulled directly from each vendor's current public pricing and help-center pages, not from vendor marketing copy or third-party roundups. Four things were compared specifically:

A note on what's not here: third-party review-site scores (G2, TrustRadius) are widely cited for “ease of use” comparisons, but weren't accessible for direct, sourced verification while researching this piece — so review-site scores are deliberately left out rather than repeated secondhand.

AT A GLANCE

Pricing and agency features, side by side

INSTANTLY

Best for agencies that want white-labeling and don't need strict per-client isolation

Instantly bundles unlimited mailboxes and unlimited warmup into every outreach tier starting at $47/month, and offers a real white-label option — a custom subdomain and logo — on its higher tiers. The catch for agencies specifically: clients with campaign access can see every campaign in the workspace, not just their own. There's no per-client data isolation.

Pros: unlimited warmup and mailboxes included, not an add-on; genuine white-label branding option.
Cons: white-labeling gated to expensive tiers; no per-client campaign isolation — a real risk if clients shouldn't see each other's data; pricing is split across four different tab-based product lines that take real effort to compare against each other.

SMARTLEAD

Best for agencies that need genuinely isolated client workspaces

Smartlead is the only platform here with a documented, isolated per-client sub-account structure — separate campaigns, leads, and email accounts per client, plus a master inbox that rolls up replies across every client account. That real isolation comes at the cost of a base plan ($39/month) that deliberately excludes CRM access, the warmup pool, and multi-workspace support, pushing most of what an agency needs into higher tiers and paid add-ons.

Pros: real per-client data isolation, unlike Instantly; master inbox for cross-client reply visibility.
Cons: warmup pool, mailbox provisioning, and inbox-placement testing are all separately priced add-ons — the real per-client cost is higher than the headline price suggests; white-labeling itself is an additional paid add-on on top.

SALESHANDY

Best for agencies that want granular per-client permission control

Saleshandy's client management system stands out for permission granularity — a three-tier system (Full, Limited, View Only) rather than a blunt on/off toggle. White-labeling and unlimited client access are gated to the Scale tier ($139/month) and above; below that, agency features aren't really available.

Pros: the most granular per-client permission system of any platform here; unlimited mailboxes and clients once on the Scale tier, per Saleshandy's own claim.
Cons: warmup runs through a third-party partner integration rather than natively; agency features require a $139/month minimum entry point; lead-finding credits are sold separately from the base plan and can add up quickly for agencies doing prospecting in-platform.

LEMLIST

Best for small agency teams that don't need white-labeling

Lemlist's Email plan includes unlimited users at a flat $55–69/month — unusual among these platforms, most of which charge per seat somewhere in their pricing. Multi-client management runs through a “Cockpit” view with per-client billing. What's missing: no white-label option was found on any official Lemlist page — no custom domain, no client-branded reporting — so agencies can't present the tool under their own brand.

Pros: unlimited users on the base plan, genuinely unusual for this category; lemwarm includes real per-mailbox health diagnostics, not just a ramp schedule.
Cons: no white-label option; the Multichannel tier needed for LinkedIn or SMS reverts to per-user pricing; pricing has changed more than once in 2026, worth reconfirming at the point of signing.

WOODPECKER

Best for agencies that want to see exactly what each client costs

Woodpecker prices its agency features per client, itemized: an Agency Panel at $27/month per active client, plus a separate White Label add-on at $5/month per active client. That's more transparent than a bundled plan, but it also means cost scales directly and visibly as client count grows, unlike ForgeSend or Lemlist's flatter models.

Pros: transparent, itemized per-client pricing — you always know exactly what a given client costs; AI-simulated warmup conversations included.
Cons: per-client fees add up quickly at real agency scale; the domain check-up tool covers SPF and DKIM but not DMARC; base pricing runs on a usage calculator rather than fixed tiers, which takes more effort to compare against flat-rate competitors.

FORGESEND

Best for agencies that want per-client cost accountability and an optional self-hosted path

ForgeSend's Agency tier — $229/month cloud or $199/year self-hosted — includes unlimited client workspaces at one flat price, with a line-item enrichment ledger that logs provider, cost, and timestamp per action so client billing comes from a real record rather than an estimate. The self-hosted option exists specifically for clients who need their data to stay off third-party infrastructure.

The honest tradeoffs: warmup is an optional paid add-on from $27/month, not bundled free the way Instantly or Lemlist include it. Self-hosting requires real technical capability — a Linux VPS, Docker, and roughly 30–60 minutes of setup per ForgeSend's own documentation — so it isn't a fit for a non-technical agency team. There's no native CRM integration yet; it's listed as a roadmap item, not a shipped feature. And ForgeSend is a newer platform than Woodpecker or Lemlist, with less third-party review history to weigh it against.

Pros: flat pricing regardless of client count; per-action enrichment cost visibility; pre-send guardrails that block launch on DNS, warmup, or list failures; self-hosting for compliance-sensitive clients.
Cons: warmup costs extra; self-hosting has a real technical bar; no CRM integration yet; smaller and newer than several platforms on this list.
