VERDICTVERIFIED

COST1 lead

If this bounces on its first send, the lead comes back automatically.

Your last outreach tool sent you a bill for this.

Hailyo is built the other way round: accountable outbound. Every lead comes with a receipt, and every email passes a check you can read.

“Verified” emails that bounced anyway
A domain that started landing in spam
Credits that vanished at the end of the month
A renewal charge you didn't see coming

Every email passes six checks before it leaves your outbox.

Not a weekly report after the damage. Hailyo checks right before each send, and an email that fails is held with the reason. It's never sent anyway, and never dropped without telling you.

The inbox is real

Every lead was verified in the last 14 days. Older than that, Hailyo checks it again before the first send, at no cost to you. Unsubscribed and bounced addresses are never emailed again.

Your domain proves it's you

The records that tell Gmail and Outlook an email really came from you must pass, checked within the last six hours. Hailyo shows each record, the fix in plain words, and how close you are to limits most tools never mention.

You're not on a blocklist

Your domain, your mailbox and every link in the email are checked against the lists inbox providers use. Hailyo also re-checks your domain every 12 hours. A confirmed listing pauses sending on that domain straight away.

Hi {{first_name}}, saw your café opened a second…

A name didn't fill in. Fix the draft and approve it again. Nothing went out.
It fits today's safe pace

No warmup network and no borrowed reputation. Each new mailbox starts slowly with real emails and builds up over three weeks. Sends are spaced out, capped per inbox provider, and only go during the lead's working hours. Once a sequence has sent 200 emails, it pauses itself if 2% of them bounce.

Three things to know before you pay a dollar.

What you pay: $1 for a 30-day Test Drive with 100 verified leads. Then Starter at $49/month for 250 leads, or Growth at $99 for 600. A search that finds nobody costs nothing.; See pricing
What if it bounces: A verified lead that hard-bounces on its first send comes back as a new lead, on your ledger, without you asking. In your first paid month, if more than 3% bounce (at least 50 sent), ask and we refund the month.; The exact terms
How to cancel: Online, in Settings, any time. We remind you 7 days before the Test Drive renews. Leads you found are yours to export, even after you leave.; No call, no email to support.

Who Hailyo isn't for.

Saying it now saves us both a month.

Agencies sending thousands a day. A mailbox here tops out at 30 a day, 50 once it earns it.
Anyone who wants a warmup network. We don't swap emails with a pool of strangers' inboxes to look busy.
Anyone who wants an AI to send on its own. You approve every email unless you switch that off.
Founders doing their own outbound who want fewer, better emails and a domain that's still healthy next quarter.

Questions burned buyers ask.

More on how it works and how it compares to Apollo.

What exactly is a “verified lead”?

One person with a checked, deliverable email address, plus their name, title and company. You're only charged a lead when the check passes. A search that finds nobody costs nothing.

What happens if a verified lead bounces?

If a lead Hailyo verified hard-bounces on its first send, you get a new lead back automatically and it shows on your ledger. That applies when the lead was verified in the 14 days before that send and your domain passed its checks at send time, up to 10% of the month's verified leads. Full terms.

Is the $1 Test Drive a trap?

No, and here's every term up front. You pay $1 today for 30 days, 100 verified leads and 2 mailboxes. Unless you cancel, it becomes Starter at $49/month for 250 leads. We email you 7 days before that first charge, and you can cancel online in Settings at any time.

What can Hailyo do in my mailbox?

Send the emails you approved and read the replies to them. You connect Microsoft 365 with Microsoft's sign-in, Google Workspace with an app password, or any mailbox over SMTP/IMAP. Disconnect in Settings whenever you like, or revoke Hailyo from your Microsoft account or delete the Google app password. More on mailbox access.

Why so few emails a day?

Because that's what keeps a domain healthy. A new mailbox sends 8 a day in week one and settles at 30 a day by week four (you can raise it to 50 once its health and replies earn it). To send more, add mailboxes on a second domain, which Hailyo walks you through. If you want thousands of emails a day from day one, Hailyo isn't for you.

Is cold email legal where I sell?

B2B cold email is legal in the US under CAN-SPAM, and in the UK and EU under conditions (PECR and GDPR legitimate interest). Every email Hailyo sends carries a working one-click unsubscribe and your business address. EU and UK contacts need a legitimate-interest note before they can be added to a sequence. You stay responsible for who you contact.
