Why should I use Phrasee to supercharge my subject lines?

Your brand’s voice.

Your brand isn’t generic. So your subject lines shouldn’t be either. Phrasee’s computational linguists write language algorithms tailored to your brand, and no one else’s.

Human sounding.

There’s nothing worse than a subject line that doesn’t make sense. With Phrasee’s advanced natural language generation technology, your subject lines sound human. Because it’s actual AI.

Awesome optimisation.

Phrasee uses advanced machine learning algorithms to quickly learn what works for your brand and your audience. The more you use it, the better your results.

ESP agnostic.

Phrasee is cloud-based SaaS, and works with any ESP on the planet. Whether you’re on SFMC, Oracle, Mailchimp or anyone else – Phrasee works alongside it. No problem!
