What PostHaste does

Everything an editorial team does.
None of the headcount.

01

Researches & Curates

Scans your niche daily. Finds the stories, data, and trends your audience cares about. Filters the noise.

02

Writes & Edits

Drafts original editions in your voice. Sharp intros, clean analysis, consistent tone every single time.

03

Grows Subscribers

Identifies growth channels, creates companion social content, and optimizes for opens and referrals.

04

Sells Sponsorships

Pitches relevant sponsors, negotiates rates, manages the ad calendar. Revenue on autopilot.

How it works

Three inputs. Then it just... goes.

1

Pick your niche

Tell PostHaste what your newsletter covers. Fintech, climate tech, London dining, remote work culture, whatever you care about.

2

Set your voice

Casual and witty? Buttoned-up and analytical? PostHaste learns your tone from a few samples and stays consistent.

3

Watch it run

PostHaste publishes on schedule, grows your list, and reports back weekly. You review when you want. Intervene when you want. Or don't.

Newsletters are the last honest channel.
Now they run themselves.

Social algorithms change. SEO rules shift. But an inbox is a direct line to someone who chose to hear from you. PostHaste makes sure that line stays alive, consistent, and growing, whether you're at your desk or on holiday.
