  2. Skipping Gmail today:
  3. too much warm-up mail landed in spam there.

Find what’s breaking delivery before you send.

One missing record is enough for Gmail to file you as spam. Most people find out when the replies stop.

A walkthrough of the free check: typing acme.io into flaiir.co/check; the results show two checks passing, three problems (SPF over its lookup limit, no DMARC record, a new domain never warmed up) and one that couldn’t be checked, with 31% of mail landing in the inbox. One click on Fix with Flaiir fixes the three problems one by one, and the inbox share rises to 94% after four weeks of warm-up.

“Delivered” can still mean spam.

If 45 of 100 land in spam, 45 people never see your offer, and every send makes your domain look a little worse.

Your sending tool sends 100 emails and reports all 100 as delivered. Flaiir checks where each one landed: 31 in the inbox, 24 in Promotions and 45 in Spam. Then Flaiir moves them out of Spam and Promotions into the inbox, and 92 of the 100 end up in the inbox.

One number, and why.

Flaiir's Overview: a yellow panel with a 91% inbox rate, the line 'Your mail is landing, except at Outlook', the one fix to do first, a 14-day chart and a live activity feed.
The real Overview, with example data. One number, the reason, and the one thing to fix.

It only touches its own emails.

Worried a warm-up tool will read your clients’ replies? It can’t.

How long to reach your daily goal?

Rush it and the domain burns; then it’s a new domain and another month of warm-up.

Your goal, cold emails a day

A bigger goal doesn’t take longer: every mailbox climbs this ramp at the same time, with Flaiir’s seed inboxes opening, replying to and rescuing its mail. Flaiir raises the number only on clean days and cuts it the day something goes wrong. Plan yours in the ramp planner

Send me your domain.

I’m Mamadou, and I build Flaiir. I’ll check it myself.

Email mamadou@flaiir.co

Before you connect.

Do you need my password?

Not for Gmail, Google Workspace, Outlook or Microsoft 365: you sign in with Google or Microsoft, and Flaiir never sees your password. Other hosts use an app password, a separate code you can revoke, stored encrypted (AES-256) and deleted when you disconnect.

How do I connect a mailbox?

Enter your email and Flaiir finds your provider. Gmail, Google Workspace, Outlook and Microsoft 365 connect with your Google or Microsoft sign-in. Yahoo, iCloud, Zoho and most other hosts connect with an app password.

How fast will my sending grow?

It depends on what you send. Cold outreach starts at 5 a day and grows about 10% on clean days; a newsletter starts at 25 and grows about 25%. Volume holds when bounces or spam placement creep up, and halves when they turn bad. Each day comes with the reason.

Can I get my money back?

Yes. If Flaiir isn't for you, email mamadou@flaiir.co within 14 days of your first payment and you get all of it back, no questions asked.

Can I stop at any time?

Yes. Every mailbox has pause and a kill switch, and disconnecting deletes the stored app password straight away.
