StrataMail Backup MX vs. Email Continuity
Two products. One question: do your users need to work during an outage event?
StrataMail offers two levels of email protection. Both queue inbound mail and redeliver automatically on recovery. The difference is what your users can do while the outage event is happening. This page helps you pick the right one.

Choose Backup MX Services If…
StrataMail Backup MX Services is the right choice when:
- Your users can tolerate waiting for mail until the primary server recovers
- Outage events are infrequent and typically short — maintenance windows, brief ISP issues
- You want the lowest-cost protection layer for a domain
- The customer has no spam filter and needs simple DNS-based fallback (Config C)
- You are protecting a domain where mail volume is low and no one will notice a brief delay
- Budget is the primary constraint and read/reply during an outage event is not required
Backup MX Services protects your reputation with senders — they never see a bounce. Your users just have to wait for recovery to see their mail.

Choose Email Continuity If…
StrataMail Email Continuity is the right choice when:
- Users need to read and respond to email during an outage event — not just after
- The domain belongs to a business where email downtime has direct operational impact
- You are protecting domains on M365, Google Workspace, or Exchange where users expect continuous access
- You are performing an M365 tenant-to-tenant migration and need mail capture and access during the DNS propagation window
- The customer has SpamWeeder Premium — native failover integration makes setup seamless
- You want to offer a premium, white-labeled service that commands higher customer pricing
- Outage events — however rare — cannot be allowed to disrupt user productivity
Email Continuity protects both your reputation with senders and your users' ability to work — no one inside or outside the organization is disrupted.

The Delivery Configuration Factor
Your spam filter setup affects which product is appropriate:
| Your Setup | Right Product | How It Works |
|---|---|---|
| SpamWeeder Premium | StrataMail Email Continuity | SpamWeeder's native multi-destination failover routes to StrataMail automatically — no DNS change needed |
| Proofpoint, Mimecast, Barracuda, or Defender | StrataMail Email Continuity | Configure StrataMail as alternate delivery in your filter admin — filter handles failover |
| No spam filter | StrataMail Backup MX Services | DNS secondary MX — StrataMail receives mail when primary MX is unreachable |
Customers without a spam filter are limited to Backup MX Services (Config C). Webmail access during outage events requires a spam filter that can route to StrataMail as a failover destination (Config A or B). This is one strong reason to pair StrataMail with SpamWeeder Premium — it unlocks full continuity capability for customers who don't have an enterprise filter.
