01

A first impression that costs nothing extra

Every email you send becomes a tiny ad for your brand, instead of for Gmail.

02

Built-in proof you are who you say you are

SPF, DKIM, and DMARC tell receiving servers (and recipients) your mail is genuinely yours.

03

Higher open rates, fewer spam folders

Authenticated mail from a custom domain lands in the inbox where free addresses get filtered.

What's inside

Everything a professional email hosting plan should include.

The bits other providers charge extra for, or skip entirely. All standard on every MailAfiniti plan.

The address

Custom-domain email

Send and receive on you@yourbusiness.com, not @gmail.com. Any registrar, any TLD: .com, .ca, .com.au, .io.

hello@yourbusiness.com
Inbox, not spam

SPF, DKIM, DMARC, auto-generated

The three DNS records receiving servers use to decide whether to trust your mail. Generated and verified for your domain when you connect, with no manual records to copy wrong.

How to set up business email on every client
Scope

Email hosting, not a productivity suite.

MailAfiniti is email, done properly. No Docs, no Drive, no Teams, no Zoho CRM bundled in, no calendar invites pretending to be a meeting platform. If you already keep documents in free Google Drive or OneDrive, you stop paying for the bundled software you don't use. Want the full picture? See our take on Google Workspace alternatives.

Looking for a side-by-side against Google Workspace, Microsoft 365, or Zoho Mail? See the full comparison.

Setup

Set up business email in 5 minutes.

Three steps. No hardware, no IT ticket, no IP warming.

  1. 01

    Verify your domain

    Sign up with your business domain. We give you a single TXT record to add at your registrar (under a minute of work).

  2. 02

    Add MX, SPF, DKIM, and DMARC records

    Copy-paste the four records into your DNS panel, then click verify once they're live. Propagation usually takes a few minutes.

  3. 03

    Send your first email

    Log into webmail or connect your existing mail client. Free migration starts the same day if you opt in.

FAQ

Business email hosting: common questions.

About the product, the setup, and the comparisons.

What is a business email server?
A business email server is the system that sends, receives, and stores email for your domain (you@yourbusiness.com). Running your own takes a Linux admin, careful DNS configuration, ongoing security patches, and IP reputation management. MailAfiniti runs the server for you, so you get the custom-domain mailbox while we handle everything underneath.
Do I need my own server to host business email?
No. Hosted business email replaces the self-managed server entirely. You point four DNS records (MX, SPF, DKIM, DMARC) at MailAfiniti and your mail flows through our infrastructure: no hardware, no software updates, no IP warming. Setup takes about 5 minutes.
Which mail protocols does MailAfiniti support?
MailAfiniti speaks IMAP4 (port 993, SSL), SMTP submission (port 587, STARTTLS), POP3 (port 995, SSL), and CalDAV/CardDAV for calendar and contact sync. Standard ports, standard auth. Any RFC-compliant mail client connects with one set of settings, which we generate for you per mailbox.
How does MailAfiniti handle SPF, DKIM, and DMARC?
When you add your domain, MailAfiniti generates the exact SPF, DKIM, and DMARC records your domain needs. You copy them into your DNS registrar, then our verifier confirms each record is live before activation. DKIM is signed on outbound by our mail servers, so authentic mail from your domain is cryptographically tagged on every send.
Is hosted email secure?
Yes. Mail is stored encrypted with AES-256 and protected by opportunistic TLS in transit. SPF, DKIM, and DMARC records are auto-generated for your domain. You paste them into your registrar and we verify them, which prevents spoofers from sending mail that looks like it came from you. Inbound mail also passes through spam and virus filtering before it reaches your inbox.
How much storage do I get per mailbox?
10 GB per mailbox on the Starter plan, 30 GB on Professional, and 50 GB on Enterprise. Storage is per-user (not shared across the team), so a busy mailbox does not crowd out a quiet one.
How does MailAfiniti filter inbound spam and phishing?
Inbound mail passes through several layers before it reaches your inbox: connection-level RBL checks against Spamhaus to block known bad senders, SPF/DKIM/DMARC authentication enforcement to stop spoofing, plus content-based spam and virus scanning. Messages flagged as spam or unsafe are quarantined so you can review and release them if needed.
Does MailAfiniti work with Outlook on desktop?
Yes. MailAfiniti speaks standard IMAP and SMTP, so Outlook (Windows, Mac, Outlook 365) connects with a one-time settings paste. We generate the exact host, port, and authentication values for each mailbox you create, and our step-by-step guides cover Outlook on every version. You can also keep using Outlook calendar and contacts via CalDAV/CardDAV.
Can I use MailAfiniti with the Gmail app, Apple Mail, or my iPhone?
Yes. The native iOS Mail app, the Gmail app on iPhone or Android, Apple Mail on macOS, Thunderbird, Spark, Airmail, and any other RFC-compliant mail client connect with the same one-time IMAP/SMTP settings. We generate the values for you per mailbox, so setup is a copy-paste, not a configuration project.
What is the uptime target?
We target 99.9% uptime. The current architecture is a single hardened cloud region with redundant compute and audit logging. Specific SLA terms (uptime credits, exclusions, response windows) are detailed in our SLA document at /legal/sla.
