Mailgun, in your routing layer. Not the bottleneck.
Connect Mailgun with API credentials, enforce per-hour and per-day quotas, and route it alongside SES, SendGrid, Postmark, and SMTP servers in a single pool.

Mailgun is strong on its own. Stronger in a multi-provider stack.
Mailgun offers solid deliverability tooling, good documentation, and straightforward pricing. Teams that run it in production usually want two things it doesn't provide out of the box: a second provider for redundancy, and a unified view across that second provider.
Mailers.io solves both. Keep Mailgun as a primary sending path, add other providers to the same pool, and get one dashboard that honours Mailgun's own reputation and policies.
Plug Mailgun in once. Operate it forever.
- Step 1
Attach Mailgun API key
Provide your Mailgun API key and sending domain. Add multiple domains or regions (EU, US) as separate sending servers.
- Step 2
Set quotas & priority
Cap sends per hour and per day per domain. Priority decides when Mailgun runs versus other pooled providers.
- Step 3
Send with unified reporting
Accepts, delivered, bounced, complained — all Mailgun events surface next to the same metrics from other providers.
What you gain by routing Mailgun through Mailers.io.
Multiple API keys
Attach per-domain or per-environment keys (prod / staging / cold) as distinct sending servers.
Quota-aware routing
Enforce Mailgun-side plan limits plus your own internal caps in one pass.
Failover to another provider
If Mailgun errors or throttles, pool members (SES, SendGrid, SMTP) take over automatically.
Shared templates & suppression
Write templates once; apply them across Mailgun and every other provider in the pool.
Authentication verification
Continuous checks against Mailgun-managed SPF and DKIM records on your sending domain.
Unified event log
Mailgun webhooks are correlated with our sends so every event lands in one timeline.
Transactional + cold separation
Keep transactional Mailgun domains isolated from cold outreach domains via routing pools.
Provider-attributed reporting
See which domain and API key produced which event. Compare against other providers you attach.
- You already run Mailgun and want a redundancy path without replacing it
- You use Mailgun for transactional and want a different provider for marketing/cold
- You need unified reporting across Mailgun and other providers
- You want quota enforcement that respects Mailgun plan limits
- Mailgun reputation and policies still apply — we orchestrate, we do not override
- Mailgun tracking features (opens/clicks, suppression) still work; we layer on top
- Sub-account structure on Mailgun maps to separate sending servers on our side
Questions answered clearly.
Mailgun is solid. Make it part of a real orchestration layer.
Attach Mailgun and start routing with quotas, failover, and unified reporting across every provider you use.
