Common questions

What is the cheapest cold email setup for 500 inboxes?

SalesBlink is cheapest in this scenario at $5,958.34 per month in total (Business plan, billed monthly), including mailboxes, domains, warmup, verification and a CRM. Reply.io is next at $5,969.34.

How much does a 500-inbox cold email stack cost per month?

Between $5,958.34 and $8,541.67 per month across the 5 tools whose published plans cover 500 inboxes, 40 emails per inbox per day and 1,000,000 prospects. That is $5.96 to $8.54 per 1,000 prospects.

How much of cold email cost is infrastructure?

Mailboxes and domains cost $4,384.67 per month in this scenario whichever sequencer you use, which is 74% of the cheapest total.

How is warmup, verification and CRM cost calculated?

Each is $0 when the chosen plan's pricing page says it is included. Otherwise we add the cheapest published option: per-mailbox warmup, pay-as-you-go verification for the full prospect list once per quarter (spread over three months), and the cheapest per-seat CRM whose limits fit. If a vendor does not say whether something is included, we price it as an add-on.

Why are some tools not in the ranking?

35 tools are listed separately for this scenario because their published plans do not cover it, they do not publish mailbox limits or prices, or they price in a currency other than US dollars. We do not estimate missing numbers.
