Moving from Mailgun to Mumara what to expect?

[beauhightow]

Hi everyone,

We currently send most of our emails through Mailgun, mostly transactional notifications and some marketing messages.

Recently our team started evaluating Mumara, especially Mumara Campaigns and MumaraONE.

For those who already migrated from Mailgun → Mumara:

• What should we expect during the transition?
• Are there infrastructure differences?
• Does deliverability change?

Any real experiences would help a lot.

Thats a very good decision we actually moved from Mailgun to Mumara Campaigns last year for one of our projects.

The biggest difference is control vs managed service. Mailgun is a fully managed SMTP/API email service, while Mumara offers two main approaches:

• Mumara Campaigns → Self-hosted or cloud deployment
• MumaraONE → SaaS platform managed by Mumara

So the experience depends on which product you choose.

Can you explain the difference between Campaigns and MumaraONE in this scenario?

 

[Christian Goliath]

Sure here’s a simple overview.

Feature	Mailgun	Mumara Campaigns	MumaraONE
Infrastructure	Fully managed	Self-hosted or your cloud server	SaaS managed by Mumara
Primary usage	Transactional API sending	Bulk campaigns + marketing/transactional + automation	Marketing/Transactional + automation
Server control	No control	Full control	Managed
IP management	Limited	Fully customizable	Managed pools or dedicated IPs
Automation features	Basic	Available via add-ons	Built-in
API integration	Yes	Yes (extensive)	Yes (extensive)

So the main difference is who manages the infrastructure.

With Campaigns, you manage it.
With MumaraONE, Mumara manages it.

One thing we rely on heavily in Mailgun is the API.

Can Mumara integrate with applications through APIs as well?

 

[Christian Goliath]

Yes, definitely.

Both Mumara Campaigns and MumaraONE provide extensive API connectivity, which is something many developers overlook initially.
Through APIs you can:

• Send emails programmatically
• Manage contacts and lists
• Trigger campaigns
• Track delivery events
• Control automations
• Fetch reports and statistics

In many setups, teams use the API to integrate Mumara with:

• CRM systems
• SaaS applications
• lead capture forms
• internal dashboards

So if you're currently using Mailgun APIs, moving to Mumara usually doesn't break your workflow.

 

[beauhightow]

Good to know. What about deliverability differences?
Mailgun usually handles reputation automatically.

 

[Christian Goliath]

That depends on which Mumara product you use.

With Mumara Campaigns (self-hosted):
You control everything, including:

• sending servers
• IP warm-up
• authentication (SPF, DKIM, DMARC)
• sending reputation

This gives more flexibility but requires more responsibility.

With MumaraONE (SaaS):
Infrastructure is handled by Mumara, so the experience feels closer to Mailgun.
However, list quality and sending practices still matter.

Did you see any performance difference after migrating?

 

[Christian Goliath]

Yes a significant difference was observed especially for high-volume sending.

Example from one of our projects:
Before (Mailgun):

• ~350K emails/day
• costs increasing with volume
• limited control over IPs

After migration to Mumara Campaigns:

• scaled to ~800K emails/day
• 3 dedicated sending IPs
• significantly lower infrastructure cost

Once the IPs were warmed properly, the system ran smoothly.
