Promotional emails that reach the inbox.

• 01

  New sending domains land in spam for the first 4–6 weeks. E-commerce brands often set up new domains for seasonal campaigns or product launches. Without warmup, those emails land in spam and the brand never knows. By the time they check, the domain is burned.

• 02

  Promotional emails get filtered to Promotions tab by Gmail. When your promotional emails land in the Promotions tab instead of the Primary inbox, open rates drop by 50-70%. Most brands don't even realize their emails are being filtered — they just see declining engagement.

• 03

  Spam complaints spike silently when reply rates drop — by the time you notice, the domain is burned. A sudden drop in reply rates often signals deliverability problems, but most teams don't monitor this closely. By the time the issue is visible, the domain needs weeks of recovery.

• 04

  Multiple marketing managers sharing one domain kills deliverability. When 5 marketing managers send from the same domain, the combined volume triggers spam filters. One bad campaign from one manager damages reputation for everyone.

• 05

  There is no visibility into inbox placement across Gmail, Outlook and corporate filters. Your emails might land in the inbox at Gmail but go to spam at Outlook. Without cross-provider testing, you're optimizing for one inbox while ignoring the rest.
