MailAfiniti vs Fastmail: Same Email, 66% Less Cost

Why Businesses Choose MailAfiniti Over Fastmail

Fastmail is built for people who love email. Fast search, keyboard shortcuts, custom rules, and a clean web interface. It's what email nerds recommend.

MailAfiniti is built for busy business owners who just want professional email that works. Set it up in minutes and get back to running your business.

Both do the job. The question is whether you need a premium email app — or a reliable business tool.

Side-by-Side Comparison

Pricing Breakdown

Fastmail Pricing

• Basic: $4/user/month ($3/month annual), 6 GB storage
• Standard: $6/user/month ($5/month annual), 60 GB storage

The Key Difference: Fastmail Custom Domain Requires $6/month

To use a custom domain on Fastmail — which is the whole point of business email — you need their $6/month plan. MailAfiniti includes custom domains on every plan starting at $2.

For a 10-person team:

• Fastmail Standard: $60/month ($720/year)
• MailAfiniti Professional: $30/month ($360/year), or $22.50/month annual ($270/year)

You save $360 to $450 per year.

Where Fastmail Wins

Webmail experience: Fastmail's web interface is genuinely best-in-class. Fast search, keyboard shortcuts, snooze, undo send. If you spend all day in webmail, you'll notice the difference.

Masked emails: Create unlimited email aliases on the fly. Great if you sign up for services with unique addresses to block spam.

Calendar and contacts: Fastmail's calendar and contacts sync well across all devices.

Privacy: No ad scanning, no tracking, open standards. Strong privacy reputation.

Where MailAfiniti Wins

Price: Custom domain email from $2/mo vs $6/mo. That's 66% less.

Automatic setup: MailAfiniti sets up SPF, DKIM, and DMARC for you. These are the DNS records that keep your emails out of spam. Fastmail makes you add them yourself. For a non-technical business owner, that's the difference between emails that land and emails that disappear.

Human support: Real people on every plan, with phone support on Enterprise. Fastmail is email-only support, no phone option.

Free migration: We move your emails for you. Fastmail gives you self-service tools and you do it yourself.

Who Should Use Fastmail

• Power users who spend hours in webmail and want the best interface
• Privacy-focused users who want masked emails and minimal tracking
• Developers who appreciate JMAP protocol support
• Teams where $7/user/month is comfortable and webmail quality is the priority

Who Should Use MailAfiniti

• Businesses using Outlook, Apple Mail, or other desktop clients
• Cost-conscious teams where $2–3/mo per user fits better than $7/mo
• Non-technical owners who need automatic setup
• Companies that want human support and hands-on migration help
• Anyone who needs custom domain email without paying a premium

Frequently Asked Questions

Is Fastmail's webmail really that much better?

Yes. If webmail is your main email app, Fastmail is noticeably better. But if you use Outlook, Apple Mail, or Thunderbird, you'll never see Fastmail's interface. Both providers deliver email to desktop apps the same way via IMAP.

Can I switch from Fastmail to MailAfiniti?

Yes. Our team moves all your emails, folders, and contacts with zero downtime. Free on Professional and Enterprise plans.

Does Fastmail auto-configure SPF/DKIM/DMARC?

No. Fastmail gives you the DNS records and you add them yourself. Takes about 10 minutes if you know DNS. If that sounds intimidating, MailAfiniti handles it for you.

Which is more private?

Both are ad-free and don't scan your emails. Both use encryption in transit. For most business users, privacy is similar between the two.

Fastmail for Business Email: What You're Actually Paying For

Fastmail's Standard plan at $6/month is built around the webmail experience. The interface is fast, polished, and genuinely better than most competitors. If email is your primary work tool and you spend hours in your inbox, that quality is real and noticeable.

But here's the practical reality for most small businesses: they access email through Outlook, Apple Mail, or their phone's default mail app. They use IMAP. The webmail interface is irrelevant to them.

In that case, Fastmail's premium is being paid for a product that never gets used. The email itself — delivery, storage, spam filtering, custom domain — is handled identically via IMAP by both providers.

MailAfiniti targets exactly this gap. Professional email, custom domain, automatic SPF/DKIM/DMARC, human support, free migration — from $1.50/mo. No premium webmail tax.

The Bottom Line

Fastmail is a premium product with a premium price. If you live in webmail and want the best email interface, it's worth $7/month.

But most businesses use Outlook or Apple Mail — not webmail. For them, Fastmail's interface goes unseen. They're paying 3–4x more for the same result: professional email on their domain. MailAfiniti gets you there from $1.50/mo with less setup hassle.
