Customer Stories

Loved by Teams Who Live in Their Inbox

From solo professionals to enterprise teams, GrapphenMail transforms how people work with email.

GrapphenMail’s AI compose feature saves me 2+ hours every day. I describe what I need in a sentence and get a perfect email. The deliverability tools are also exceptional — our open rates jumped 40% after setting up DMARC and BIMI.

Sarah Chen
Head of Communications, TechVentures Inc.

We switched from GSuite for our team of 50. The shared mailboxes and internal comments completely eliminated our need for a separate helpdesk tool. Plus the booking pages integrated directly into our support workflow.

James Okafor
VP of Customer Success, DataFlow Systems

The inbox placement testing alone is worth the price. We discovered our emails were landing in promotions at Outlook — the warmup tool fixed it in two weeks. Now we consistently hit 98% inbox delivery.
