Will my emails arrive? How nanimail takes care of deliverability

When you choose where to host your business email, the question that truly matters isn't how many features the service ships. It's simpler and more serious: if you write to a customer, does your message land in their inbox?

It's a fair question, especially for a service you're just getting to know. So we'll answer it head-on: this is what nanimail does, today, so your emails arrive.

What decides whether an email arrives

When you send an email, the receiving server decides within seconds what to do with it: inbox, spam folder, or rejection. To decide, it looks mainly at three things:

• Authentication: can it verify the message really comes from your domain and that nobody tampered with it along the way?
• Reputation: do the servers it came from have a track record of sending legitimate mail?
• Behavior: does this sender generate bounces and spam complaints, or mail people actually want?

Deliverability is the work of taking care of those three things every day. Let's go one by one.

Your domain is authenticated from day one

When you connect your domain to nanimail, the guided setup includes the five DNS records modern email expects:

• SPF, which declares which servers are allowed to send mail on behalf of your domain.
• DKIM, a digital signature proving the message left your domain and wasn't modified in transit.
• DMARC, which tells the rest of the internet what to do with an email pretending to be yours.
• MX, so mail addressed to your domain reaches your inbox.
• The return path, so bounces come back through the right channel.

And it's not optional: nanimail verifies the records are in place before enabling sending. No half-configured domain sends from our platform, not yours and not anyone else's.

We send through infrastructure with years of reputation

nanimail doesn't improvise sending servers. Your emails go out through Postmark, an infrastructure specialized in email delivery with years spent building and protecting its reputation, and one of the providers we list publicly on our subprocessors page.

In practice, it means your messages leave through servers the major email providers already know and treat with trust. A young service like ours doesn't start from zero: it stands on a foundation with years of proven good behavior.

We look after the neighborhood

On any shared email platform, reputation belongs to everyone. If a single account starts sending spam, the filters don't discriminate carefully: the damage splashes onto everybody else.

That's why we watch every organization's bounce and spam-complaint rates, with thresholds considerably stricter than the industry's. If an account starts misbehaving, we pause its sending long before it reaches levels that could affect anyone else's delivery.

Put simply: your email's delivery doesn't depend on your neighbor's behavior.

Sending limits protect you too

You may have noticed our plans have a daily recipient limit and wondered whether it will feel tight. The limits are sized for a business's real email (replying to customers, sending quotes, coordinating with suppliers), and they play a role that isn't obvious at first glance: they make nanimail useless to anyone who wants to send bulk mail.

That benefits you directly. A platform whose sending patterns are healthy keeps a healthy reputation, and a healthy reputation is exactly what makes your emails arrive.

Your part of the deal

We'd be less than honest if we said everything depends on us. Deliverability is shared work: we provide the authentication, the infrastructure, and the monitoring; the content and the recipients come from you.

The golden rule is simple: write to people who expect your email. Replying to customers, handling orders, and following up on real conversations builds your reputation. Sending to purchased lists or to contacts who never asked to hear from you destroys it, and no provider can save you from that.

In short

"Will my emails arrive?" is the right question, and it deserves a concrete answer. At nanimail: your domain is fully authenticated before it can send, your messages leave through infrastructure with years of reputation, we monitor the platform so no neighbor harms your delivery, and the limits are designed so spam has no room here. The rest we build together, one email at a time.
