Fastmail is the only listed option that directly covers email and calendar use. It starts at $3 and is aimed at people who want paid email, custom domains, and offline mail and calendar access. The other products below handle documents, PDFs, or faxing—not email-client features. We include them because the available alternatives list is limited, but they are not like-for-like eM Client replacements. Before switching, check eM Client’s device limits and mobile-sync reports.
01Why people leave eM Client
Version upgrades cost extra
One Reddit thread says an eM Client 10 user was quoted $45 to upgrade to version 11 and wanted clearer non-AI benefits.
AI features have a separate fee
A commenter cited a $3 monthly AI add-on and questioned which version 11 features require it; the thread did not resolve that.
Clunky Microsoft 365 experience
One Reddit commenter described eM Client as clunky with M365 and said users can feel left behind if they do not pay for newer versions.
02The alternatives, ranked by fit
- Paid email service
FastmailFastmailFastmail is the closest fit if you want to leave eM Client’s desktop-app model for a paid email service. It starts at $3 and is aimed at people moving from Gmail, using a custom domain, or needing offline mail and calendar access. The pricing page does not specify its full plan limits, so check those before moving accounts.
Trade-off: It is an email service, not a like-for-like desktop client replacement.
8.1/10from
€3/mo - Browser documents
Word for the webWord for the webWord for the web is not an email alternative, but it fits if your reason for leaving eM Client is really a need to simplify a Microsoft account-based workflow around documents. The listing says it offers browser-based document editing and collaboration, with a free plan and pricing from $1.67. It does not replace email or calendar features.
Trade-off: You give up the email, contacts, and calendar role eM Client fills.
6.5/10from
$1.67/mofree plan - Budget office suite
WPS OfficeWPS OfficeWPS Office makes sense only if you are replacing a broader desktop-work setup, not just your inbox. Its listing describes document and PDF tools for personal users and small teams, with a free plan and pricing from $2.49. The listing also warns that the free tier is limited and paid-plan costs are not fully transparent.
Trade-off: It does not provide an email-client replacement.
6.4/10from
$2.49/mofree plan - PDF workflows
SmallpdfSmallpdfChoose Smallpdf if the practical job you need to move is PDF editing, signing, or shared document work—not email. The listing says it covers common PDF jobs and has a free plan, with paid pricing from $7. Its free-use limits and paid-plan costs narrow the value, so it is not a substitute for eM Client’s email and calendar tools.
Trade-off: No inbox or calendar replacement; free use is limited.
6.6/10from
$7/mofree plan - PDF task toolbox
iLovePDFiLovePDFiLovePDF suits people whose switch is really about consolidating PDF tasks into one app. The listing describes varied PDF tools, a free plan, and a $5 starting price. It flags unclear free limits and privacy concerns, so check what the plan includes before relying on it for team workflows. It does not handle the email-client job.
Trade-off: PDF-focused, with unclear free limits and privacy concerns.
7.8/10from
€5/mofree plan - Team PDF editing
Foxit PDF EditorFoxit PDF EditorFoxit PDF Editor is relevant if your reason for leaving eM Client is a need for cross-platform PDF editing, eSign, or batch tools. The listing starts at $10.83 and says AI-credit caps and tier-gated tools affect value. It is a document suite, not a mail client, so it will not replace eM Client’s inbox or calendar.
Trade-off: Higher starting price; AI credits and tools are tier-gated.

Questions people ask
What is the closest eM Client alternative in this list?
Fastmail is the closest match because the listing covers email plus offline mail and calendar access. It starts at $3 and targets people moving from Gmail or using a custom domain. It is an email service rather than a like-for-like desktop client, and the published information does not publish its full plan limits.
Why are PDF apps listed as eM Client alternatives?
They are not direct email alternatives. The available alternatives list includes several document and PDF products but only one email service. We include them for readers whose underlying need is document editing, signing, or collaboration; none replaces eM Client’s inbox and calendar role.
Does eM Client charge separately for its AI features?
A Reddit commenter in a discussion about version 11 cited a $3 monthly AI add-on and asked which features required it. The thread did not settle whether specific features, including the MCP server, require that add-on. Check eM Client’s current pricing and feature details before upgrading.
