What to do: switch on signing in Microsoft 365. We show you where.

Why it matters

Most small businesses don't know their email is at risk until a customer says "your email went to spam".

Google, Microsoft and Yahoo now junk or reject more email from domains that aren't set up properly. Scammers can also send emails that look like they came from you.

Land in inboxes

Quotes, invoices and replies reach your customers instead of their spam folder.

Stop fakes in your name

Make it much harder for scammers to send emails pretending to be you.

No jargon, ever

Every problem comes with a plain-English explanation and the exact fix.

How it works

Calm waters in three steps.

  1. Check your domain for free

    Type in your website address and get a grade from A to F with what to fix.

  2. Let Harbour keep watch

    Email providers send daily reports about mail sent in your name. We read them so you don't have to.

  3. Hear about problems early

    If something breaks, or someone starts faking your address, you get an alert in plain English with the fix.

Pricing

Questions

Good to know

Do I need to be technical?

No. Harbour explains everything in plain English and tells you exactly what to change, step by step. If you can log in to where your website's domain is managed, you can do it.

What does the free check look at?

It reads the public settings for your domain that other email systems look at: whether fake emails in your name get blocked (DMARC), who's allowed to send for you (SPF), whether your email is signed (DKIM), and whether you can receive email. Nothing is installed and nothing changes.

Will it change anything on my domain?

Not by itself. Harbour only suggests changes, and you decide whether to make them.

Do I need a card for the free trial?

No. Every plan has a 14-day free trial with no card needed, and you can cancel any time.

What happens to the domains I check?

We look them up and show you the result. We don't store the domains you check or add you to any list.
