How it works

From incoming email to sent reply

01
Connect your Gmail.
Link your Gmail account and Super Mailer immediately starts watching your inbox for emails that need a response. Setup takes under two minutes.
02
KOIRA context shapes the draft.
Super Mailer pulls your business name, tone, products, and customer context from KOIRA to generate a reply that sounds exactly like you — not a robot.
03
Approve and send.
Every draft lands in the KOIRA approval queue so you review before anything goes out. One click to approve, edit, or discard — total control, zero effort.
Smart Drafting

Context-aware emails,
not generic templates.

Super Mailer reads the incoming email thread and cross-references your KOIRA business profile — industry, tone of voice, products, and customer history — before writing a single word. Every draft is unique to that conversation, not a copy-paste template. You get replies that sound human because they're built on real business context.

Approval Workflow

Every draft reviewed
before it leaves your inbox.

Super Mailer never sends without your sign-off. All generated drafts flow into the KOIRA approval queue where you can read, tweak, approve, or reject with a single click. It's the speed of automation with the confidence of full human oversight — especially important for customer-facing and sales emails.

Re: Bulk order question — 200 units
Hi Marcus, thanks for reaching out about a bulk order of 200 units — we'd love to make that happen. Our standard lead time for orders over 100 units is 5–7 business days, and I've flagged your enquiry for our sales team to send across a custom quote by end of day. In the meantime, feel free to reply here if you have any other questions.
Reviews

Real businesses, fewer emails to write

“I was spending 90 minutes a day on support emails. Super Mailer cut that to about 20. The drafts genuinely sound like me — my customers have no idea it's AI-assisted.”

“We handle a high volume of B2B inquiries and every email needs to sound professional. Super Mailer nails our tone every time. Approval queue means nothing slips through unapproved.”

“Honestly the ROI was immediate. I'm a one-person consultancy and I was drowning in client emails. Now I review 10 drafts in the time it used to take me to write one.”
