Frequently Asked Questions

What plan do I need to send 50,000 emails a month?

On Instantly, the entry Growth plan ($47/mo, 5,000 emails/mo) falls well short; you’d need the Hypergrowth plan ($97/mo, 125,000 emails/mo and 25,000 uploaded contacts) to comfortably cover 50k with headroom. On Smartlead, the Base plan (6,000 sends/mo) is also too small; Pro ($94/mo billed monthly, 30,000 contacts) is the realistic entry point at this volume. On Woodpecker, you buy a monthly tier of contacted prospects: assuming roughly 6 sequence emails per contacted prospect, 50,000 emails works out to about 8,300 prospects/month, which needs the 10,000-prospect tier at $188/mo (billed monthly), meaningfully more than Instantly’s or Smartlead’s flat-rate plans at the same volume.

Do I need more mailboxes to hit 50,000 emails a month, regardless of which tool I use?

Yes, the sending tool doesn’t remove the underlying deliverability math. Industry data on cold email sending puts the sweet spot at roughly 50–75 emails per mailbox per day before reply rates flatten and spam complaints climb. At 50,000 emails/month (~2,300/day on a 22-day sending month), that means around 30 warmed-up mailboxes spread across 15–20+ separate sending domains, regardless of whether you’re on Instantly, Smartlead, or Woodpecker. All three tools help manage rotation and warmup, but none of them substitute for having enough mailbox and domain infrastructure at that volume.

Which tool has the strongest deliverability tooling at scale?

Instantly leans on built-in inbox rotation, a native warmup network, and a deliverability score dashboard included on its plans. Smartlead’s high-volume answer is a dedicated IP add-on plus its “SmartServers” sending infrastructure, aimed at agencies running many client domains at once. Woodpecker takes a different approach: human-like sending-pattern throttling designed to avoid the sending patterns spam filters flag, which fits its agency-first positioning. None of the three eliminates the need for properly warmed mailboxes and domain diversity described above.

Which of the three is built for agencies managing multiple client accounts?

Woodpecker and Smartlead are the more agency-oriented picks: Woodpecker ships white-label reporting and dedicated agency/client management tooling, while Smartlead offers a white-label API for agencies and unlimited seats on its Pro-and-up plans. Instantly supports agency use too (its Light Speed plan adds SISR dedicated sending infrastructure for high-volume senders), but its core positioning (unlimited mailboxes per workspace with an optional 450M+ contact database, sold as separate Credits plans) leans more toward in-house sales teams running their own campaigns.

Editorial assessment

What this means for your team

  • Audit reports: we found no SOC 2 or ISO/IEC 27001 statement on any vendor’s site. For regulated or enterprise buyers, request security documentation before committing.
  • Working offline: Instantly, Smartlead and Woodpecker don’t document an offline mode. Details are in the Offline mode row above.
  • Where your data lives: Smartlead lets you choose Australia. This matters for teams hiring across the EU, UK or Australia.

Instantly: worth knowing

  • SecurityWorkspace owners can force every user in the workspace to log out of all devices, e.g. after a security incident. source
  • SecurityInstantly's DPA states the service is not designed for HIPAA or PCI DSS data, so health or card data should not be put into it. source
  • RemoteThe Unibox mobile app lets team members answer interested leads from their phones. source

Smartlead: worth knowing

  • SecuritySmartlead's DPA says data is stored in the AWS Sydney region, though other user data may be processed in several other countries. source
  • RemoteOnce a campaign exists, it can be fully managed (inbox, leads, analytics) from the mobile app; campaigns are created in the web app. source

Woodpecker: worth knowing

  • SecurityWoodpecker stores data on OVH-hosted servers; the ISO 27001 certification cited belongs to the hosting provider, not Woodpecker itself. source
  • SecurityWoodpecker's two-step login sends a verification code to the account email address. source
  • SecurityWoodpecker states full recovery after a complete database breakdown should not exceed 6 hours, with backups every 6 hours. source

Hover or tap “source” to see the exact wording we relied on. “Not published” means we could not find the vendor saying it on its own site; it doesn’t mean the feature is missing. Plan names are the lowest plan the vendor says includes the feature. Security · Offline · Remote vs office · Download the data
