Cold email sending platform with unlimited mailboxes and warmup, a 450M+ contact database, and credits priced per verified email found.
Outbound teams running volume across many mailboxes who need warmup, inbox rotation and bounce protection in the same tool that holds the lead data. The outreach plans publish unlimited email accounts and unlimited warmup from the $47/mo Growth tier, and the help centre publishes per-action credit costs so list costs are modellable. The deliverability guide documents concrete guardrails, including automatic campaign pausing above a 5% bounce rate.
Credits expire on a clock, not just at cycle end: the help centre states credits expire two months after purchase on monthly plans and one year after purchase on annual plans, so buying a large block ahead of a campaign can waste it. Sending and data are sold as separate product lines - outreach plans, credit plans and bundles - so a working setup is usually two line items, and the pricing page carries conflicting figures for the Hypergrowth and Supersonic tiers. Capacity is capped by uploaded contacts as well as sends (Starter and Growth allow 1,000 uploaded contacts and 5,000 emails/month), the FAQ states exceeding 100,000 emails or 25,000 leads requires an upgrade, and the Deliverability AI Agent requires the Hyper Growth plan or higher.
Pros
Cons
The help centre publishes four rates: 1 credit for a verified work email found by Instantly's own data, 2 credits for one sourced from data partners, 0.5 credits per fully enriched profile, and 0.25 credits per lead verified. It states no credits are consumed when a verified work email is not found, and puts the practical average at roughly 1.5 credits per verified work email across a mixed list.
Yes, and on a clock rather than at cycle end. The help centre states that on monthly plans credits expire two months after purchase if unused, and on annual plans credits expire one year after purchase. Annual billing delivers all credits upfront with a 10% discount, which means a large annual block has a hard twelve-month window. Budget to consume credits rather than stockpile them.
The deliverability guide states campaigns are automatically paused when bounce rate exceeds 5%, enabled by default, with the check running only after a campaign has sent at least 200 emails; the threshold is configurable. It recommends keeping bounces below 2% and advises a few dozen cold sends per mailbox per day rather than hundreds. SPF, DKIM, DMARC and one-click unsubscribe are treated as mandatory for bulk senders.
The pricing page shows a Start free button and says no credit card is required, but it does not describe any free tier limits. The help centre refers to a free trial that includes 100 credits for testing verification, which is a trial rather than an ongoing free tier. The lowest published ongoing price is the Growth outreach plan at $47/mo, or $37.60/mo on annual billing.
