§ 02 · WHERE EACHN° 002

Where each one wins

Pick Reoon if your monthly volume sits at 10k or below.
At 10k Reoon is $11.90 vs KillBounce $20. The gap is small in absolute terms ($8) but Reoon wins the sticker-shock test at trial sizes. If you want the lowest possible rate for the first few lists, Reoon is the honest answer.
Pick KillBounce if your monthly volume climbs past 500k.
At 1M KillBounce is $750 vs Reoon $972, a $222 saving per million emails. The curve flips in KillBounce’s favour at scale because of the Enterprise tier discount.
At 100k, pick on something other than price.
The two are within $4 at the 100k tier, which is statistical noise. At that volume, pick on dashboard polish, API documentation quality, support responsiveness, or an existing integration you need. The $4 is not the decision.

§ 03 · WHAT BOTHN° 003

What both providers do the same

SMTP handshake against the recipient mail server, not just MX lookup
Catch-all / accept-all domain detection
Disposable and throwaway address filtering
Role-based account detection (support@, info@, admin@ etc.)
Bulk CSV upload with progress tracking
Credits never expire, no monthly commitment
Free trial credits (100 on signup for both)

§ 04 · WHAT WEN° 004

What we don’t know and won’t claim

We have not independently tested Reoon on an identical sample list. Accuracy claims from either side (ours or theirs) deserve a side-by-side test on your own list before you commit at scale. Both offer a signup credit pool large enough to run that test.

§ FAQ · Common questionsN° 100

Answers to the questions teams ask first

Q · 01

Is Reoon actually cheaper than KillBounce?

At low volumes (10k and below), yes: Reoon is $11.90 vs KillBounce $20. At mid volumes (100k), the two are within $4 of each other. At high volumes (1M), KillBounce is $750 vs Reoon $972, a 23 percent saving. Pick by the volume you actually run.

Q · 02

Why would I pick KillBounce if Reoon is cheaper at my tier?

For most trial-sized workloads, you shouldn’t pick on $8. The real decisions are dashboard polish, API docs, support, and integration fit. We publish a transparent price ladder so you can switch tiers predictably as your volume changes; most competitors hide the mid-tier numbers behind a sales call.

Q · 03

Do both offer a credit-back guarantee on wrong verdicts?

KillBounce has a credit-back guarantee on hard-bouncing deliverable verdicts. We have not independently verified Reoon’s policy on the same shape; check their current terms before you commit volume.

Q · 04

Can I migrate between the two?

Yes. Both export standard CSV. A list verified on one provider can be imported into the other without reverification. If you want a second-opinion pass, both charge only for addresses they haven’t seen before.

Q · 05

Which has better API documentation?

KillBounce publishes REST documentation at /api-docs with request / response examples. We have not benchmarked Reoon’s API documentation quality against ours.
