Marketing email infrastructure

Stop letting one campaign put every email at risk

Separate marketing traffic from business-critical email, control your sending reputation and find delivery problems before they damage campaign performance.

Separate marketing and transactional email

Keep promotional campaigns away from receipts, login codes, account alerts and other essential emails. Separate sending environments prevent marketing volume from affecting messages customers need to receive.

Own the reputation behind your campaigns

Send through dedicated IPs and authenticated domains instead of relying on shared pools affected by senders outside your control. Build a reputation tied to your own sending practices.
