Exactly how it works
From photo upload to Instagram post — here's every step of the process in detail.
Upload photos to Google Drive
You get a dedicated Google Drive folder. Drop in your product photos whenever you like — upload 30 at once and Postman will drip them out one per day for a month. No schedule to manage.
Receive your daily email
Every day you get an email with 3 post variations for that day's photo. Different captions, different text overlay styles. You pick the one that feels most you — one tap, from your phone.
Pick your favourite option for today's post:
Goes live on Instagram
Once approved, your post publishes automatically to Instagram. The caption, the hashtags, the text overlay — all done. You can also choose to download and post manually if you prefer.
Full visibility. Total control.
Your Postman dashboard shows your post queue, approval history, and Instagram performance — all in one place. Manage everything from your browser.
Small businesses love Postman.
"I used to spend Sunday evenings planning my Instagram for the week. Now I upload 30 photos once a month and forget about it. My engagement has actually gone up."
"As a one-woman business I can't afford a social media manager. Postman is the next best thing — it actually understands my brand and writes captions I'd write myself."
"Setup took 10 minutes. The approval emails are so easy — I just tap my favourite on my phone while I'm having my morning coffee. Worth every penny of the $10."
One price.
No surprises.
Everything included. No tiers, no add-ons. Just consistent Instagram presence for less than the cost of a single boosted post.
