Mailgun is a developer-focused transactional email service that handles sending, parsing, and tracking at scale. It is widely used for product notifications, password resets, receipts, and high-volume marketing where deliverability and detailed logs matter. Connecting Mailgun to WellPlan lets you route campaign and transactional email through your Mailgun domain, with delivery, open, click, bounce, and unsubscribe events flowing back into workflows. Teams keep WellPlan's audience and content tools while Mailgun handles deliverability infrastructure, dedicated IPs, and detailed event tracking that's especially helpful for diagnosing inbox placement issues.
Features
Common use cases
Send transactional notifications at scale
A SaaS platform sends invoice receipts and password reset emails through Mailgun, triggered by WellPlan workflows. Mailgun's deliverability infrastructure keeps these critical emails out of spam, and event logs help debug if a customer reports a missing message.
Run high-volume marketing
A media company sends a daily newsletter to a large list. WellPlan composes and segments the campaign while Mailgun delivers it through dedicated IPs, with engagement events flowing back to power follow-up workflows by SMS or WhatsApp.
Diagnose deliverability problems
An e-commerce brand investigating low open rates uses Mailgun's logs to see which mailboxes accepted, deferred, or rejected each message. Findings feed back into WellPlan list hygiene rules so future campaigns clean themselves automatically.

Frequently asked questions
How is Mailgun different from SendGrid?+
Both are transactional and marketing email services with strong deliverability. Mailgun has historically had a stronger developer and API focus, while SendGrid has more marketing UI. Either works well with WellPlan; the choice often comes down to existing accounts, pricing, and team preference.
Do I need DNS access?+
Yes. Adding SPF, DKIM, and DMARC records is required to authenticate sending and reach the inbox reliably, especially after Gmail and Yahoo tightened sender requirements in 2024. Mailgun walks you through the exact records during domain setup.
Will bounces and unsubscribes sync back to WellPlan?+
Yes. Mailgun's webhooks send delivery, bounce, complaint, unsubscribe, and open/click events to WellPlan in near real time. WellPlan updates the contact record, pauses sequences for hard bounces, and respects unsubscribes across the system automatically.
Can I use Mailgun for one-to-one sales email?+
Mailgun is designed for application-driven sending rather than personal one-to-one email. For one-to-one sales email from a real mailbox, the Gmail or Outlook integration is a better fit. Use Mailgun for campaigns, transactional, and high-volume sends.
