Why mixing the two streams is dangerous
Promotional email and transactional email behave nothing alike. A big campaign gets variable engagement, the occasional spam complaint, and bursts of volume. A receipt or password reset is expected, opened, and rarely reported. If both go out under the same sending reputation, a rough promo can drag down the deliverability of the email a customer is actively waiting for.
Separated identities, one brand
SmartMailing sends your two streams under separate sending identities with isolated reputations, while keeping them under one brand and one dashboard. A complaint spike on a campaign stays contained to the promotional reputation. Your transactional mail keeps its own clean track record.
- Promotional sends warm and build their own reputation.
- Transactional sends are prioritized and kept on a separate, protected identity.
- Both authenticate from your own verified domain (DKIM, SPF, DMARC).
Keep the campaign and the receipt apart, and the receipt always lands.
You still see it all in one place
Separation happens under the hood. In the dashboard you still get one unified view of everything you send — you simply get the safety of two reputations instead of one fragile shared one.
