The short answer

Smartlead : Agency focused sender with unlimited mailboxes and client workspaces from about $39 a month, a cheaper start than PrimaryHub's $100 plan. From $39/mo
Instantly : The most widely used high volume sender, with warmup and a unified inbox from $47 a month and far more review history. From $47/mo
MailDeck : Managed inbox infrastructure with DNS and warmup set up for you, for teams that need the mailboxes built rather than a sequencer. From $30/domain/mo

Why people look past PrimaryHub

It is a young brand with no Capterra or G2 reviews yet, and the volume figures on its site (28,000+ mailboxes, 2,000+ domains) are the vendor's own. The $100 entry price is well above Smartlead or Instantly starter plans, so it pays off mainly for teams running many inboxes. AI tagging needs your own provider key and a paid account with that provider.

What we noted

No independent review history yet
$100 entry price is high for small senders
No built in lead database

Not the right fit for

Solo senders with one or two inboxes who only need a cheap starter plan
Buyers who want a lead database bundled in (it has none)
Teams that want an established vendor with independent review history

Worth keeping in mind: Warmup is provider matched rather than pooled: Google Workspace inboxes warm only with real Google Workspace inboxes and Microsoft 365 with Microsoft 365, which keeps them away from random SMTP servers where spam traps sit. It is unlimited on every plan, and AI reply tagging runs on your own DeepSeek, Claude, OpenAI, Gemini or Groq key, so there are no marked up AI credits.

What each one does differently

$39/mo Free trial MCP API

Instantly

$47/mo Free trial MCP API

Why it comes up: The most widely used high volume sender, with warmup and a unified inbox from $47 a month and far more review history.

Stands out: Warmup, unibox, and volume send with hosted MCP and a public API, plus an AI Recruiting Agent that finds candidates from a job link and emails them.

Watch out: Deliverability still depends on your domains and inboxes, not the tool alone.

Best for

Outbound recruiting teams sending at volume
Agencies running many sending accounts
Desks that need warmup plus a unibox

MailDeck

$30/domain/mo API

Why it comes up: Managed inbox infrastructure with DNS and warmup set up for you, for teams that need the mailboxes built rather than a sequencer.

Stands out: One US Microsoft tenant holds 100 Outlook inboxes, so 1,000 inboxes is 10 domains at the tenant rate.

Watch out: Sale rates sit under a higher regular rate. Google extra mailboxes cost $2.99 to $3.50 each. SMTP is a different stack.

Best for

Agencies buying Outlook inboxes by the hundred
High-volume senders mixing Outlook, Google, and SMTP
Teams that want setup and domain replacement included
