SmartLead
Our primary sending sequencer. Multi-inbox cold email at scale, with white-label sub-accounts for every client.
In our stackLast reviewed July 17, 2026
What SmartLead actually is.
SmartLead is a cold email sending platform built to run large volumes of outbound through many inboxes at once. It centralizes inbox warmup, sequencing, and reply handling instead of stitching those together from separate tools. Every plan lets you connect unlimited sending mailboxes; what changes as you move up tiers is how many emails you can send and how many contacts you can store, not how many inboxes you rotate through.
Getting a new inbox sending well takes real setup: authentication records, warmup, and sequence tuning before deliverability holds up. The built-in CRM is a Kanban board tied to the inbox, good for tracking replies but not a swap for a dedicated CRM if that's what a team needs.
What it does
- Unlimited sending mailboxes on every plan, across Google and Outlook.
- Automated warmup that simulates opens, reads, and replies to build sender reputation.
- Auto-configures SPF, DKIM, and DMARC records for each sending domain.
- Master inbox pools replies from every campaign and client in one view.
- Built-in Kanban CRM synced to campaigns and the inbox.
- White-label sub-accounts so agencies can run separate client workspaces.
- API and webhooks for pushing sends and pulling reply data into other tools.

The tools we'd run next to SmartLead, and what each pairing covers.
Its job inside client systems.
SmartLead is where client campaigns actually send. We run it at the account root, each client as a white-label sub-account under clients.leadlinepartners.co, so their prospects never see us. Sequences, inbox rotation, warmup, reply routing. We drive it from the command line day to day and fall back to the API when something custom is needed. Deliverability lives or dies here, so it gets watched closely: bounce rates, open patterns across days, reply sentiment over reply count.
Pricing, without the fiction.

The bill is driven by two things: monthly email sends and stored contacts, not by inbox count, since inboxes are unlimited on every plan. That makes SmartLead cheap for teams rotating many mailboxes but expensive to scale past Base once a sequence with multiple follow-up steps pushes send volume past 6,000/month. CRM access and API/webhooks are included starting at Pro ($94/mo); the actual gates on Pro are private infrastructure ($39/mo add-on) and client workspaces ($29/mo add-on), and both stay paid through Unlimited Smart too, only becoming included at Unlimited Prime ($379/mo). What Unlimited Smart buys over Pro is uncapped contacts and a warmup pool that's no longer a paid add-on, not CRM or API access. Annual billing cuts the effective rate by about 17% across plans.
Choose it, or skip it.
Choose it if
- Teams running cold email at real volume who need many sending inboxes without paying per-inbox: SmartLead does not charge per mailbox on any plan, so a team running 20+ inboxes pays the same plan fee as a team running 3.
- Agencies managing outreach for multiple clients: Unlimited Prime ($379/mo) includes 3+ client workspaces, 3 SmartServers, and a dedicated Slack channel, which is built for that use case.
- Teams that want deliverability tooling (warmup, rotation) bundled into the sending tool instead of stitched together from separate vendors.
- Buyers on a starter budget who want to test cold email before committing: Base is $39/mo with a free trial, though it caps at 6,000 sends and 2,000 contacts a month.
Skip it if
- Teams sending under a few hundred emails a month, or running a single sales rep's outbound: the plan tiers and inbox-rotation features are built for volume, and the cost isn't justified at that scale.
- Buyers who need a native, deep CRM: SmartLead's CRM is a basic Kanban board included from Pro ($94/mo) up; it isn't available at all on the entry Base plan and isn't built to replace a dedicated CRM.
- Teams whose bottleneck is data quality, not sending: SmartLead is a sending and sequencing platform, not an enrichment or verification source, so it still needs a data tool feeding it clean contacts.
If not SmartLead, then what.
- Instantlyfrom ~$37-47/mo (Growth/Starter plan, billed monthly or annually); modular add-ons (leads, CRM) push real cost to $100-4
Choose Instantly when you want a similar unlimited-sending-account model but prefer its specific analytics dashboard and pricing structure; the two are close competitors on the same core mechanic.
- lemlistfrom $55-69/mo flat (Email plan, unlimited users, annual/monthly); Multichannel $87-109/user/mo; Enterprise custom quote
Choose lemlist when personalization at the individual-email level (custom images, video, dynamic landing pages) matters more than raw send volume.
- Reply.ioEmail Volume from $179/mo flat ($159/mo annual, 10k contacts); Multichannel from $99/user/mo ($89 annual)
Choose Reply.io when you need multichannel sequencing (email plus calls and LinkedIn steps in one sequence) built natively rather than assembled from separate tools.
Asked in real client work.
What actually caps you on the cheapest plan?
Base ($39/mo) caps at 6,000 email sends and 2,000 stored contacts per month, with 2,000 verified prospect emails included. Teams doing real sequence volume (multiple follow-ups across a list) hit the send cap well before the contact cap.
Does SmartLead charge per email account/inbox?
No. SmartLead advertises unlimited email accounts on every plan, so cost scales with sends and contacts, not with how many inboxes you rotate through.
What do you get for the jump from Pro to Unlimited Smart?
Pro ($94/mo) tops out at 90,000 sends and 30,000 contacts, with CRM and API access already included, though private infrastructure ($39/mo) and client workspaces ($29/mo) stay paid add-ons. Unlimited Smart ($174/mo) raises sends to 150,000/month, removes the contact cap, includes a premium warmup pool, and keeps those same private infrastructure and client workspace add-on fees, since neither becomes free until Unlimited Prime.
Is there a free trial, and does it require a credit card?
SmartLead lists a free trial on its pricing page and a free sign-up flow (app.smartlead.ai/sign-up). The pricing page confirms no credit card is required to start.
What's different about the top plan besides higher sending limits?
Unlimited Prime ($379/mo) is the plan built for agencies: it includes 3 SmartServers, OAuth, 3+ client workspaces, private infrastructure access, and a dedicated account manager, not just a bigger send cap.
