EmailBison
SequencersUpdated Oct 28, 2026Pick EmailBison if you send more than 100,000 cold emails a month and want one flat price with unlimited teammates. Pick Smartlead if you only need the tool that sends the emails. EmailBison is a cold email sequencer, the tool that sends a lead a series of emails over days. It prices by the number of emails sent instead of the number of contacts stored. The Base Plan costs $599 a month billed monthly for 500,000 emails a month. That price bundles in isolated IPs, a mail-sending address only one sender uses. It also bundles in warm-up, a slow ramp that builds a new inbox’s trust with mail providers.
The verdict
EmailBison sells one sequencer plan, the Base Plan, at $599 a month billed monthly. That price includes 500,000 emails a month, isolated infrastructure, email warm-up and an API, the way your code talks to the tool. No per-seat fee, a charge added for each teammate on the account, applies at any size. Leads, workspaces and teammates stay unlimited on that single plan. Sending past 500,000 emails a month means buying extra monthly buckets of send volume. Ask EmailBison for that price before you plan on it. Smartlead, the live sequencer alternative, prices by contacts stored and emails sent instead of emails sent alone. Base costs $39 a month billed monthly for 2,000 contacts and 6,000 sends. Pro and Smart sit in between, with more contacts and sends.
Prime costs $379 a month billed monthly, lifts the contact cap, and sends 500,000 emails a month with 3 SmartServers, dedicated sending servers, included. Every Smartlead plan sells the sequencer only; inboxes get bought from a separate seller. The math: at 500,000 emails a month, EmailBison costs $599 a month billed monthly and Smartlead Prime costs $379 a month billed monthly. $599 minus $379 = $220 a month more for EmailBison, before any inbox gets added to Smartlead’s side. The number of inboxes a 500,000-send month actually needs is not fixed on either price list. The full assembled cost of Smartlead plus inboxes is not priced as one figure. Pick EmailBison once send volume runs well past 100,000 emails a month and isolated IPs, warm-up and unlimited teammates in one price weigh more than a lower sequencer rate. Pick Smartlead when a sequencer alone is the job, since its tiered plans cost less up to its own 500,000-send Prime tier. Either way, inboxes come from a separate seller: Premium Inboxes for hundreds of inboxes, InboxKit for smaller counts.
What users say
“@Nickeubanks Email Bison for scale (500k email/mo) SendKit should work for smaller scale.”
“@coldemailchris I’m sorry email bison really didn’t do it for me. I came from smartleads and really wanted to believe that email bison had something. It just wasn’t there. …”
Best for
Teams sending well past 100,000 emails a month that want isolated IPs, a mail-sending address only one sender uses, and a warm-up pool bundled into a single price with no per-seat fee.
Not for
Skip it under 100,000 emails a month, where Smartlead’s tiered plans cost less for the same sends. Skip it too when a lower price weighs more than bundled infrastructure, since inboxes still come from a separate seller either way.
Pricing truth
$599 a month billed monthly buys EmailBison’s Base Plan, which includes 500,000 emails a month, isolated infrastructure with dedicated IPs, email warm-up, an API and dedicated support through a private Slack channel, all in the same price. No per-seat fee applies at any size; leads, workspaces and teammates stay unlimited. Past 500,000 emails a month, EmailBison sells extra monthly buckets of send volume. Ask EmailBison for that price. Smartlead’s four tiers price by contacts stored and emails sent. Base costs $39 a month billed monthly for 2,000 contacts and 6,000 sends. Prime costs $379 a month billed monthly for unlimited contacts and 500,000 sends, with 3 SmartServers, dedicated sending servers, included. Pro and Smart sit in between. Inboxes are not part of any Smartlead plan. For the inbox side of the stack, InboxKit charges a flat $3.00 a mailbox a month billed monthly, or $2.50 a mailbox a month billed yearly, with no minimum purchase and no volume tiers. Premium Inboxes drops its rate as volume grows. Start Up costs $3.50 per inbox every 4 weeks for 1 to 249 inboxes, and the rate drops at 250 inboxes and again at 1,250. ScaledMail’s Google mailboxes cost $3.50 each a month billed monthly, with no contract. InboxKit bills a month at a time and Premium Inboxes bills every 4 weeks, so line up the billing basis before you compare the two.
When we use it

- Run isolated infrastructure with dedicated IPs, a mail-sending address only one sender uses, bundled into one monthly price.
- Warm up new inboxes with a built-in warm-up pool, sending small amounts of mail slowly so a new inbox builds sender reputation, the trust score mail providers track per inbox, before full volume starts.

How to wire it
- Count emails sent a month instead of contacts stored. EmailBison’s $599 a month billed monthly bills by that number alone.
- Pick EmailBison once that count runs past 100,000 a month and isolated IPs weigh more than a lower sequencer price.
- Check Smartlead’s tiered plans first if the sequencer alone is the job: Base at $39 and Prime at $379, both a month billed monthly, with Pro and Smart in between.
- Price inboxes on a separate seller either way. InboxKit runs $3.00 a mailbox a month billed monthly, or $2.50 billed yearly, for smaller counts. Premium Inboxes drops its per-inbox rate at hundreds of inboxes.
- Ask about the price of additional monthly buckets before sending past 500,000 emails a month. EmailBison does not list a price for them.
Margin notes
- At the full 500,000 emails a month, EmailBison’s $599 a month billed monthly costs $220 a month more than Smartlead Prime, with isolated IPs and warm-up included.
- One $599 a month billed monthly price covers unlimited leads, workspaces and teammates.
- “Email Bison” and “EmailBison” name the same product and the same $599 a month billed monthly plan.
- Smartlead’s tiered plans all sell the sequencer only. Inboxes, domains and warm-up time still need a separate buy, from InboxKit, Premium Inboxes or ScaledMail. ScaledMail’s Google mailboxes cost $3.50 each a month billed monthly.
