Editorial

Editor’s take

HiFlyer Digital positions itself as a retention-specialist agency built by a former VP of Retention at billion-dollar retailers. The site emphasizes advanced email and SMS automation, segmentation, and personalization rather than acquisition. Claims 150+ clients and $425M in generated revenue, though detailed case studies are limited. The founder's background and retention-first philosophy are the main differentiators.
