The Best MailStore Alternatives for Small Businesses (2025)
MailStore has been a popular email archiving solution for years. But it has limitations — particularly for small businesses that don't want to manage on-premises servers or pay enterprise prices. This guide compares the top alternatives for 2025 based on price, features, ease of use, and deployment model.
Why people look for MailStore alternatives
MailStore Server is a solid product, but common reasons businesses switch include:
- On-premises requirement. MailStore Server runs on a Windows server you maintain. If you don't have (or don't want) on-premises infrastructure, it's not a fit.
- Per-user pricing adds up. MailStore starts at around €49/user/year (5-user minimum). For 20 users, that's nearly €1,000/year.
- No cloud-native option. MailStore SPE (Service Provider Edition) exists, but it's designed for MSPs, not direct small business use.
- Limited modern features. No AI search, no browser-based viewer without the web client add-on, and no native support for uploading standalone PST/MBOX files.
- Windows-only. The server component requires Windows Server. The client is Windows-only.
Evermail
Best for small businesses that want cloud-based email archiving with instant search, no servers, and transparent pricing.
Evermail is a modern, cloud-native email archive built for teams that need to store, search, and share old email — without running any infrastructure.
Key features

- Full-text search across all emails, attachments, and metadata.
- Threaded conversation view in the browser.
- Role-based team access — share archived mailboxes without sharing credentials.
- Three security tiers: standard encryption, bring-your-own-key (BYOK), and zero-access encryption.
- AI-powered summaries on paid tiers.
- MCP endpoint for AI assistant integration (Claude, Copilot).
- EU-hosted on Azure, GDPR-compliant.
Pricing
- Free: €0/month — 1 GB storage, 1 archive.
- Starter: €4.99/month — 5 GB, 3 archives.
- Pro: €9/month — 20 GB, unlimited archives, AI summaries.
- Team: €29/month — 50 GB, 5 users, shared workspace.

- Direct OAuth import from live mailboxes coming soon but not yet available.
Barracuda Email Archiving (Cloud)
Best for mid-size businesses that want a well-known brand with compliance features and are willing to pay enterprise pricing.
Barracuda offers cloud-based email archiving as part of its broader security platform.
Key features
- Cloud archiving with eDiscovery and legal hold.
- Integration with Microsoft 365 and Google Workspace.
- Compliance search and audit trails.
- Policy-based retention.
Pricing
Starts at approximately €4–6/user/month (often requires annual commitment). Minimum user counts and bundled pricing make it expensive for small teams. Pricing is not publicly listed — you must request a quote.
- Enterprise compliance features (eDiscovery, legal hold, audit trails).
- Direct integration with major email platforms.
- Established vendor with enterprise support.
- Expensive for small businesses — 10 users can cost €500–700/year.
- Opaque pricing — no self-serve signup.
- Overkill for teams that just need to search old email archives.
- Complex setup compared to upload-and-search solutions.
Mailbird (Desktop Client)
Best for individuals who want a better desktop email experience — not a true archiving solution.
Mailbird is a Windows email client, not an archiving platform. It gets mentioned as a "MailStore alternative" in some lists, but it serves a different purpose.
Mailbird doesn't archive email independently. It connects to live email accounts. It can't import PST/MBOX files for archive search, and it doesn't provide compliance, retention, or team access features.
ArcTitan (by TitanHQ)
Best for MSPs and IT-managed businesses that need compliance archiving with central management.
Starts at approximately €3.30/user/month with minimum commitments. Multi-tenant management for MSPs. Good compliance and eDiscovery features.
- Competitive pricing for larger teams.
- Good compliance and eDiscovery features.
- MSP-friendly multi-tenant management.
- Designed for MSPs — direct small business setup can be complex.
- No standalone file upload (PST/MBOX) — designed for live mailbox archiving.
- Less intuitive UI compared to modern tools.
