Emailable details checked against their public pages on October 28, 2026. Sources

Emailable is a dedicated email verification service. You buy credits in packs from 5,000, they never expire, and unknown results are refunded when a list finishes. It offers an API, a signup widget and integrations with 50+ platforms.

InboxSure is also a dedicated verifier, but it does not use credits. Pro is a flat $49 a month for unlimited lists of up to 10,000 addresses, with syntax, DNS/MX and SMTP mailbox checks and catch-all, disposable and role-based detection.

The choice mostly comes down to how often you verify and whether you need an API.

What it costs in practice

Emailable's smallest pack is 5,000 credits for $38, and 1 credit verifies one address. Verifying 10,000 addresses a month costs up to $76 at that rate; Emailable offers volume discounts on larger packs, and its subscription takes 15% off.

InboxSure Pro costs $49 for that month, and the same $49 for a month with three lists of 10,000.

Where InboxSure is better

  • Better value at steady volume. At Emailable's published rate of $38 per 5,000 credits, 10,000 verifications a month cost up to $76, before volume discounts. InboxSure Pro is $49 however many lists you run.
  • No credit maths. There are no packs to size and no refunds to wait for. Every list on Pro is covered.
  • Free plan without a cap. Emailable gives 250 credits once. InboxSure's free plan lets you verify lists of up to 50 addresses as often as you like.
  • Free deliverability tools. Check SPF, DMARC and MX records with InboxSure's free tools, no account needed.

Where Emailable is better

  • Occasional use. If you verify one small list a few times a year, a 5,000-credit pack that never expires can cost less than a monthly plan.
  • API and integrations today. Emailable has a REST API, a signup-form widget and 50+ integrations now. InboxSure's API for Pro is coming soon; today it works by file upload.
  • Compliance. Emailable states SOC 2 Type II certification. If your procurement requires SOC 2, Emailable meets that today.
  • Very large lists. Emailable packs go up to 1,000,000 credits. InboxSure Pro handles up to 10,000 addresses per list.

Which should you choose?

Choose Emailable if you verify rarely, need an API or signup widget, or require SOC 2.

Choose InboxSure if you verify lists every month and want one flat price with no credits to manage.

Either way, you can see how InboxSure handles your own data for free: lists of up to 50 addresses cost nothing, and results come back as Deliverable, Risky, Undeliverable or Unknown with the reason. InboxSure reports Unknown when a mail server will not give a clear answer, rather than guessing.
