Connects with your entire email ecosystem
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.
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.
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.
