What is the best multi-provider alternative to Mailgun?
Score is a multi-SMTP routing and campaign layer that sits above providers like Mailgun — it routes mail across Mailgun, Amazon SES, SendGrid and others using weighted rules and automatic failover, then adds the lists, segmentation, and deliverability monitoring that a pure sending API leaves out. So you’re never dependent on one provider’s reputation, pricing, or uptime.
Mailgun is a capable, developer-friendly sending provider with strong APIs for delivery, validation, and inbound routing. But it is one provider: your deliverability, your costs, and your uptime are all tied to a single pipeline, and when Mailgun’s shared IP reputation dips, your campaigns feel it.
Where Mailgun still makes sense
If you want a single, well-documented sending and validation API and you’re comfortable with one provider owning your deliverability, Mailgun is a dependable choice — especially for transactional sending and teams that value its email-validation tooling. The same single-pipeline trade-off applies to other raw senders like Amazon SES and Postmark, which also own the infrastructure your mail flows through.
Where Score pulls ahead
Resilience, economics, and tooling at volume. Routing across multiple providers means no single point of failure and the freedom to send the bulk of your mail through the cheapest healthy provider at any moment — the same model offered by a dedicated multi-ESP platform such as Ongage, but with campaign and segmentation tooling built in rather than billed separately. You can keep Mailgun in the mix — Score just makes sure you’re never dependent on it. Per-provider deliverability analytics and reputation alerts give you the visibility to act before inbox placement slips, so you can start routing across providers in minutes.
Frequently asked questions
Is Score a good Mailgun alternative?
Score is a strong alternative for teams that want to avoid being locked to a single sending provider. Rather than replacing Mailgun outright, Score can route through Mailgun alongside other providers like Amazon SES and SendGrid, with weighted rules and automatic failover — so a reputation or pricing problem with any one provider no longer stalls your sending. Score also adds campaign and segmentation tooling on top of raw sending.
Can I keep using Mailgun with Score?
Yes. Score is a routing and campaign layer that sits on top of your SMTP providers, so you can add your existing Mailgun account as one of several providers. Many teams keep Mailgun for some traffic while spreading the rest across other providers to balance cost and reputation.
How does Score's pricing compare to Mailgun?
Score charges $15/month plus $0.30 per 1,000 emails over the included 10K, billed purely on volume sent. Mailgun uses volume-tiered monthly plans with an included allotment and overage charges [VERIFY: confirm current Mailgun tiers]. For higher-volume senders, routing through low-cost providers under Score typically reduces total sending cost while adding campaign tooling Mailgun charges separately for.
What happens if my sending provider has an outage?
With a single provider like Mailgun, an outage or reputation drop halts your campaigns. Score monitors each connected provider and automatically fails over to a healthy backup provider, so delivery continues without manual intervention.
Does Score handle deliverability monitoring?
Yes. Score reports deliverability per provider rather than only in aggregate, and raises reputation alerts so you can shift volume away from a degrading provider before it affects inbox placement.
