MailAfiniti vs Amazon WorkMail: An Alternative Before 2027

TL;DR: AWS has confirmed Amazon WorkMail is being discontinued: no new customers after April 30, 2026, and full end of support on March 31, 2027. After that date, WorkMail mailboxes, contacts, calendars, and the admin console become inaccessible. MailAfiniti is a managed business email alternative starting at $1.50/mailbox/month (annual), with SPF/DKIM/DMARC records generated for you and free migration on Professional and Enterprise plans, well ahead of WorkMail's flat $4/user/month rate.

Amazon WorkMail Is Shutting Down: What Happens to Your Email?

If you're searching for an Amazon WorkMail alternative, you've probably seen the announcement: AWS is ending Amazon WorkMail. As of April 30, 2026, WorkMail no longer accepts new customers, and on March 31, 2027, AWS ends support entirely. After that date, the WorkMail console, mailboxes, and all stored data (emails, contacts, calendars, and attachments) become permanently inaccessible. (Source: Amazon WorkMail end of support.)

If you're an existing WorkMail customer, this isn't urgent today, but it's not optional either. The earlier you plan the move, the less disruptive it is. MailAfiniti is a managed email host built for exactly this situation: a real mailbox replacement (inbox, contacts, calendar), not a DIY infrastructure project.

Side-by-Side Comparison

Amazon WorkMail Pricing vs MailAfiniti

Amazon WorkMail uses a flat, pay-as-you-go rate: $4 per user/month, including 50 GB of mailbox storage, with no contracts or minimum commitments. (Pricing reflects WorkMail's published rate; AWS is no longer accepting new signups as of April 30, 2026.)

MailAfiniti's plans:

If your team doesn't need the full 50 GB WorkMail bundled in, MailAfiniti's Starter or Professional tiers cost significantly less for the mailbox sizes most small teams actually use. If you do need 50 GB across the board, MailAfiniti's Enterprise tier costs a bit more per mailbox, but adds SPF/DKIM/DMARC records generated for you and free migration, neither of which WorkMail offered as a headline feature.

3-Year TCO: 10-Person Team

For teams that don't need 50 GB per mailbox, MailAfiniti's Starter and Professional tiers cost 25–62% less over three years than WorkMail's flat rate. For teams that do need the full 50 GB, MailAfiniti's Enterprise tier costs about 25% more over three years, but that gap covers SPF/DKIM/DMARC setup and free migration, both handled for you as part of the switch.

SPF, DKIM, and DMARC: Setting Up Email Authentication After WorkMail

When you move to a new email host, your domain's SPF, DKIM, and DMARC records need to point to the new provider. Otherwise your emails may land in spam, even if they worked fine on WorkMail.

MailAfiniti: We generate all three records for you the moment you connect your domain, with the exact values ready to paste into your registrar and guided setup along the way.

Amazon WorkMail: Email authentication setup was a manual DNS task, not a guided onboarding step. If you're migrating away, you'll need new SPF/DKIM/DMARC records for your new provider regardless, and MailAfiniti generates these as part of onboarding.

How to Migrate from Amazon WorkMail to MailAfiniti

1. Sign up for a MailAfiniti trial and add your domain.
2. Share your WorkMail mailbox access for each user you want moved.
3. We run an IMAP sync: emails, folders, and contacts transfer in the background.
4. Update your DNS: MX, SPF, DKIM, and DMARC records pointing to MailAfiniti. We generate the exact values for you.
5. Run both in parallel for a short overlap window to catch any stragglers, then decommission WorkMail.

Migration is free on Professional and Enterprise plans. See our email migration guide for the full step-by-step, including DNS cutover timing.

What About Migrating to Microsoft 365 or Google Workspace Instead?

If your team is moving off WorkMail anyway, you may be weighing the bigger office suites too. Microsoft 365 and Google Workspace are valid options if your team actively uses Outlook desktop, Teams, Docs, or Drive, but both cost considerably more per user than a focused email host if email is all you need. See MailAfiniti vs Microsoft 365 and MailAfiniti vs Google Workspace for the full breakdown. If WorkMail worked fine for your team as a standalone mailbox, with no Active Directory and no AWS-specific integrations, MailAfiniti is the closer like-for-like replacement.

When to Pick MailAfiniti vs Sticking with WorkMail (For Now)

Pick MailAfiniti if:

• You're an Amazon WorkMail customer planning your move before March 2027
• You want SPF/DKIM/DMARC records generated for you instead of configuring them yourself
• You want free migration handled for you, not a self-service export
• Your team doesn't rely on Active Directory integration

Stick with WorkMail for now if:

• You're inside the support window and not ready to migrate yet, but start planning, since the deadline doesn't move
• Your organization depends on Active Directory integration that you haven't replaced yet

Frequently Asked Questions

Why is Amazon WorkMail shutting down?

AWS announced it is ending support for Amazon WorkMail. New customer signups stopped on April 30, 2026, and AWS will end all support on March 31, 2027. After that date, the WorkMail console, mailboxes, contacts, and calendars become inaccessible. (Source: AWS documentation)

When do I need to migrate off Amazon WorkMail?

Existing customers can continue using WorkMail until March 31, 2027. Experts recommend starting migration well ahead of that date. DNS changes, mailbox syncing, and testing take time, and waiting until the deadline risks a rushed, disruptive switch.

I can't access my Amazon WorkMail account. What are my options?

If you're having trouble accessing WorkMail, or simply don't want to wait for the 2027 deadline, you can migrate to MailAfiniti now. We sync your existing mailbox data via IMAP and generate the new DNS records your domain needs.

What's the cheapest alternative to Amazon WorkMail?

MailAfiniti starts at $1.50/mailbox/month on annual billing (Starter, 10 GB), less than half of WorkMail's flat $4/user/month rate. For teams that need WorkMail's full 50 GB per mailbox, MailAfiniti's Enterprise tier ($5/mailbox/month) is close in price but adds DNS authentication setup and free migration.

Can I migrate from Amazon WorkMail to Microsoft 365 or Google Workspace instead?

Yes: both are valid destinations if your team uses Outlook desktop, Teams, Docs, or Drive daily. They cost more per user than a focused email host. See MailAfiniti vs Microsoft 365 and MailAfiniti vs Google Workspace for pricing comparisons.

Will I lose my emails, contacts, and calendar when I migrate?

No. Our team runs an IMAP sync that transfers emails, folders, and contacts to MailAfiniti. Migration is free on Professional and Enterprise plans. Calendar data should be exported from WorkMail separately before migration, and we'll guide you through this during onboarding.

Does MailAfiniti support Outlook and Apple Mail like WorkMail did?

Yes. MailAfiniti works with any email client over IMAP/SMTP, including Outlook, Apple Mail, Thunderbird, and mobile mail apps on iOS and Android.

How does Amazon WorkMail pricing compare to MailAfiniti?

WorkMail charges a flat $4/user/month for 50 GB of storage. MailAfiniti's plans range from $1.50–$5/mailbox/month (10–50 GB), so smaller mailbox needs cost significantly less, while matching WorkMail's top storage tier costs a bit more, with SPF/DKIM/DMARC setup and free migration included.

The Bottom Line

Amazon WorkMail's shutdown gives existing customers until March 31, 2027, but the migration work doesn't shrink by waiting. MailAfiniti offers a managed mailbox replacement with SPF/DKIM/DMARC records generated for you, free migration on Professional and Enterprise, and pricing that beats WorkMail's flat rate for most team sizes.
