From one sentence to a sale you can trace.
Four steps, each one leaving a record you can read: what was found and why, what was checked, what was sent and when, and what it earned.
Describe who you want. Hailyo looks now, not in last year's database.
Type it the way you'd say it: by what their website says, the tools it runs on, the kind of business, or a company you'd like more of. Hailyo searches the live web when you ask, and every match comes with the quote, the page and the date that qualified it.
Some things can't be seen from public websites. When that's the case, Hailyo says so and suggests something findable instead of pretending.

Every inbox is checked before you see it. You get the receipt.
The address format, the mail server, whether the inbox exists, whether the domain accepts anything (a catch-all), and whether the person ever unsubscribed or bounced. You only use a lead when the check passes, and if a verified lead hard-bounces on its first send it comes back automatically.
Coming from Apollo? Bring your list.
Import an Apollo export or any CSV. Hailyo removes duplicates and anyone on your do-not-contact list, and re-checks up to 5,000 rows a month for free, so you can see how many “verified” emails would have bounced before you send a single one. Imported leads don't use your lead balance.

You approve. Your mailbox sends. Slowly enough to stay healthy.
Cold email only ever goes out from mailboxes you connect, never from a shared Hailyo server. Each email passes six checks right before it sends, and anything that fails is held with the reason.
Your mailbox, your rules
Hailyo can
- Send the emails you approved
- Read replies to those emails
- Spot bounces and out-of-office replies
Hailyo won't
- Send anything you didn't approve (unless you switch approval off for a step)
- Use your mailbox to warm up anyone else's
Connect Microsoft 365 with Microsoft's own sign-in, Google Workspace with an app password, or any mailbox over SMTP and IMAP. To revoke access, disconnect in Settings, remove Hailyo from your Microsoft account, or delete the Google app password.
A pace your domain can survive
- · New mailboxes send 8 a day in week one, 18 in week two, 28 in week three, then 30 a day. You can raise a healthy mailbox to 50.
- · Sends are spread out with random gaps of one to five minutes, capped per inbox provider, and only go out on weekdays during the lead's working hours (default 8:00 to 17:00, skipping public holidays in their country).
- · Sending cold email from the domain your customers and invoices use? Hailyo warns you, limits it to 20 a day, and walks you through setting up a second domain instead.
- · Domains younger than 30 days are limited to 10 a day per mailbox.
Hailyo pauses itself when something looks wrong
| When | What pauses |
|---|---|
| 2% hard bounces | that sequence |
| 3% hard bounces | that mailbox |
| 3 blocks from one provider in a day | that mailbox, then the domain if it spreads |
| Gmail spam rate 0.3% | the domain |
| Listed on Spamhaus | the domain, immediately |
| SPF, DKIM or DMARC failing | the domain, until it's fixed |
Bounce rates count once at least 200 emails have gone out. Every pause tells you why, what to fix, and lets you re-check in one click.
Watched between sends, too
- · Your domain's records are re-checked every six hours.
- · Blocklists, including Spamhaus, are checked every 12 hours.
- · Every week, Hailyo sends a test email from each mailbox to its own test inboxes at Gmail, Outlook and Yahoo and records whether it reached the inbox, promotions or spam.
- · Each domain and mailbox gets a health score where every lost point has a reason and a fix.
See what each email earned.
Replies are sorted for you: interested, later, not interested, meeting booked. Out-of-office replies push the next step back; unsubscribes and bounces stop the sequence on their own.
Meetings
Put your Calendly or Cal.com link in an email. When a lead books, Hailyo marks the meeting and stops their sequence.
Vouchers
Give every lead their own code. When a code is redeemed, the revenue lands on the ledger next to the email that earned it.
