About MailFast AI Cold Email Generator
What Is MailFast AI Cold Email Generator
MailFast is a small web app for sales reps, founders and freelancers who send cold email but stall at the blank page. You paste a lead's profile link, pick a use case, and the tool hands back a short email written for that one person.
The pitch rests on its training set. The makers say the model learned from more than 270 cold emails that pulled high reply and conversion rates, so the AI cold email writer copies proven structure instead of starting from a generic prompt. It also lifts details from the lead's profile and company site, which is where the cold email personalization actually comes from.
Two limits matter before you pay. MailFast writes copy and nothing else, so it does not send messages or track opens, and you still need an inbox or a separate email outreach tool to run a campaign. The product also looks dormant as of October 2026: mailfast.me now redirects to an unrelated temporary email service, and the team's last public activity dates to 2024.
Getting Started
- Buy a generation pack on the site and check out with the email address you want tied to the account.
- Log in with that same address. There is no separate signup step.
- Paste a lead profile link, choose one of the four use cases, and generate the email.
- Copy the draft into Gmail, Outlook or your sending platform, edit the opening line, and send.

Key features
One-Click Email Generation
You supply a lead profile link and the tool returns a full email, subject line included, without a prompt to write. That matters for people who know their offer but freeze on wording. The output is short by default, closer to four or five sentences than a page.
Lead Profile and Website Extraction
MailFast reads the lead's profile and company site to pull names, roles and product details, then works them into the copy. This is the difference between real personalization and a first-name merge field. Accuracy depends on how complete the public profile is, so thin LinkedIn pages produce thinner emails.
Four Outreach Use Cases
The app splits generation into product promotion, lead generation, content promotion and customer feedback. Each mode changes structure and call to action, so a feedback request does not read like a sales pitch. You can ask support for a fifth use case, but that depends on the team responding.
Trained on 270+ High-Converting Emails
The model was built around a set of cold emails the makers describe as high conversion. In practice that shows up as familiar patterns: a specific observation, one clear benefit, a low-friction ask. Treat the conversion claim as the vendor's own, since no independent benchmark is published.
Spam and AI-Detection Wording
MailFast says its output scores 0% on AI detectors and avoids spam-trigger phrasing. The claim is unverified and detector scores shift between tools. What you can check yourself is length, link count and subject line, which are the parts filters weigh most.
Pros and cons
Pros
- Cuts drafting time to seconds for anyone who already knows the offer and the audience.
- Pulls real detail from a profile link, so the AI email generator produces something more specific than a template.
- Four use cases give noticeably different structures instead of one pitch with swapped nouns.
- Buying more credits is simple: check out again and the emails land on the same account.
Cons
- The site appears offline. mailfast.me redirects to an unrelated temp mail service, so new buyers may have no way in.
- No sending, scheduling or reply tracking, which means MailFast covers only the writing half of an outreach stack.
- No refunds. Plans are sold as generation batches, so unused credits are money you cannot recover.
- No API and no bulk upload, so volume work means pasting links one at a time.
