Hi community,

I’m currently using Mautic and would like to configure and use two different ESPs at a same time (Email Service Providers)

### My goals:

1. I want to send emails using either ESP based on my choice.
2. While creating an email or mail campaign, I’d like to see an option (e.g., dropdown) like:  
**“Select ESP: [SparkPost | InboxGini]”**
3. Based on this selection, Mautic should use the appropriate mail transport.

### Questions:

- Is this possible using the existing Mautic interface?
- can this be achieved via a custom plugin that:
  - Adds a new field (e.g., ESP selector) in the Email UI
  - Saves this metadata
  - Hooks into the `EmailSendEvent` and switches mailer based on this field?

### Tech background:

- I’m comfortable developing Symfony plugins and customizing Mautic.
- If this needs to be developed from scratch, I’m happy to contribute — just looking for any guidance or starting points.

Thanks in advance for your support!

What are the most obvious situations, where you need to have different providers?

- different brands / senders in the same instance
- different setup for marketing / transaction mails

What else?
