Warn before freeze
Escalate risky sending with graded warnings, appeal paths, and export access.
Comparison
PulsePigeon vs Mailgun
For teams that need transparent operations, PulsePigeon focuses on regulated-mail operations: controls, evidence, and predictable lifecycle decisions. This page is not a claim that Mailgun lacks any feature.

What PulsePigeon emphasizes
Focusprovider failoverBuilt for auditable SaaS mail operations.
Focusdelivery event replayBuilt for auditable SaaS mail operations.
Focusspend caps before surprisesBuilt for auditable SaaS mail operations.
Bill what was sent
Meter message sends with idempotency-aware accounting, not ambiguous contact surprises.
Show delivery evidence
Expose event logs, webhook delivery attempts, SLO burn, and provider health.
Make exit possible
Keep suppressions, templates, and delivery history portable for compliance review.
Migration
Switch without losing compliance evidence.
Import suppressions, templates, and delivery history into a review queue before production traffic moves. Keep critical transactional mail isolated until the new path has proven reputation.
Concept mapping
Mailgun concepts, mapped to PulsePigeon
ConceptRoutes for inbound message handlingTraffic-class routing and reputation controls for outbound lane isolation
ConceptTags for message categorizationPersonalized batch sends (1 to 100 items per request) with per-item idempotency keys
ConceptWebhook signing key verificationSigned status webhooks with retry and dead-letter handling
These are concept-level mappings drawn from PulsePigeon's own implementation, not a claim about Mailgun's current API shape. Confirm the Mailgun side against its own docs before treating it as settled.
Decision guidance
When Mailgun may still be the better fit
Mailgun's routes solve inbound parsing, which PulsePigeon does not attempt to replace. Migrate for outbound sending if delivery event replay and spend-cap warnings matter more to your team than inbound routing, since that stays on Mailgun or a separate service either way.
Before you switch
Questions worth asking your own team
These are prompts for your own internal review, not a scorecard against Mailgun. Verify current vendor behavior directly before treating any answer as settled.
Reputation isolationDoes our current setup mix transactional and marketing traffic on the same sending identity? A single bad marketing send can delay or block password resets and invoices if they aren't isolated onto separate lanes and IP pools today.
Engineering overhead for templatesHow much time goes into coding, compiling, and maintaining raw HTML or Markdown templates in-house versus using a visual builder? PulsePigeon manages templates through its API with variable validation and lint checks, not a drag-and-drop editor — worth confirming that trade-off fits your team before switching.
Delivery visibilityHow do bounce, complaint, and delivery events reach your team today — polling, a dashboard, or signed webhooks with retry and dead-letter handling? Confirm your current setup gives engineers enough signal to debug a failed send without opening a support ticket.
Unsubscribe and suppression handlingIs opt-out tracking and hard-bounce/complaint suppression built into your sending path, or does your team maintain that database by hand? This is easy to underestimate until a compliance review asks for evidence.
Migration effortCan you swap an API key and library wrapper, or does moving providers mean touching your notification codebase directly? Most providers, including PulsePigeon, use a proprietary request shape — budget for an integration pass and a dual-write cutover, not a one-line config change.
