MailFast Review: An AI Email Writer to Save Your Sanity?
Let’s be honest with each other. How many times have you stared at your inbox, seen 47 unread messages, and just whispered, “I’ll get to that tomorrow”? I’ve been there. More times than I can count. My inbox often feels like a digital dumpster fire, a chaotic mix of urgent requests, newsletters I don’t remember subscribing to, and follow-ups that require a delicate, professional touch I just don’t have at 4 PM on a Tuesday.
We’re all drowning. And for years, the only solution was to just… drown faster. Work longer. Sacrifice your lunch break to the email gods. But lately, a new kind of life raft has appeared on the horizon: the AI email writer. I’ve been in the SEO and traffic game for a long time, so I've seen my share of “game-changing” AI tools. Most are underwhelming. But I kept hearing whispers about an app called MailFast, so I decided to put my cynicism aside and see if it could actually help tame the beast.
What Exactly is MailFast, Anyway?
In the simplest terms, MailFast is an AI-powered assistant that helps you write emails. Think of it less as a robot that writes for you and more like a brilliant, multilingual intern who’s amazing at creating first drafts. You give it some basic instructions—a few bullet points, a general idea—and it spits out a well-structured, coherent email in seconds.
Its whole pitch is to help you “write smart and save time,” which, let’s face it, is the holy grail for pretty much any professional these days. It promises high-quality emails, faster replies, and support for pretty much any language you can throw at it. A bold claim. So, does it live up to the hype?
Putting MailFast to the Test: My First Impressions
Getting started was surprisingly simple. No clunky downloads or labyrinthine setup menus. It’s clean, it’s intuitive, and you can get going almost immediately. The interface is pretty minimalist, which I appreciate. I don’t need more clutter in my life.
The first feature I played with was the standard email generation. I needed to send a follow-up to a potential client about a proposal. Normally, this would take me 10-15 minutes of agonizing over every word to sound keen but not desperate. I fed MailFast a simple prompt: “Follow up with John about the SEO proposal I sent last week. Ask if he has any questions and suggest a quick 15-minute call next week to discuss.”
What it produced in about five seconds was… impressive. It was polite, professional, and hit all the key points. It even included a nice closing line. Was it perfect? No. But it was an 85% solution that I could tweak to 100% in under a minute. That’s a win.
But the real magic, for me, was the Reply Mode. You can take an incoming email and have MailFast draft a response. This is incredible for those tricky emails where you need to be diplomatic or when you’re just too mentally fried to formulate a polite “no.”

The Good, The Bad, and The AI-Generated
No tool is perfect, right? After using MailFast for a couple of weeks, I have a pretty good feel for its strengths and where it could use a little work.
Where MailFast Really Shines
The time-saving aspect is not just marketing fluff. It’s real. I found myself clearing out those “quick reply” emails in batches, turning an hour of tedious work into about 15 minutes. It’s also a massive confidence booster for anyone who isn’t a native English speaker. The ability to generate grammatically correct, natural-sounding emails in multiple languages is a huge advantage for global teams and freelancers. I tested it with some Spanish and French prompts, and my multilingual friends confirmed the outputs were solid. The sheer ease of use is another major plus; you don’t need a tech degree to figure it out, which can't be said for every new tool on the block.
A Few Caveats and Realities
Okay, let’s get real. The biggest trap with any AI writer is the temptation to become lazy. If you just copy, paste, and send, your emails will start to sound a bit generic. The AI provides a fantastic starting block, but you are still the ghost in the machine. It’s your job to add that personal story, that inside joke, that final human touch that builds real connection. Relying on it completely is a mistake.
The free plan is also more of a taster than a main course. At 10 emails per month, it’s enough to let you see the potential but you'll hit that limit fast if you're a heavy user. It's a smart business model, but something to be aware of. Also, and this is a personal pet peeve, having to “Contact me” for custom pricing always feels a bit like a blind date. Just give me the numbers! But I get it, enterprise needs are different.
Let's Talk Money: MailFast Pricing Breakdown
So, what's the damage to your wallet? The pricing structure is refreshingly straightforward. I’ve put it into a simple table below.
| Plan | Price | What You Get |
|---|---|---|
| Free | $0 / month | 10 emails per month. Perfect for a test drive. |
| Professional | $9 / month | 200 emails per month. The sweet spot for most professionals. |
| Custom | Contact for Price | Variable number of emails. For teams and power users. |
Is the Professional plan worth $9 a month? In my opinion, absolutely. Think about it. How much is an hour of your time worth? If this tool saves you even one or two hours a month—and it likely will—it's already paid for itself. It’s less than the cost of a couple of fancy coffees and infinitely better for your productivity.
Is an AI Email Writer Like MailFast Right for You?
This is the big question. I think these tools are a massive help for a few specific types of people:
- The Overwhelmed Professional: If your job involves a high volume of email, this is a no-brainer. Salespeople, project managers, customer support, exec assistants… you know who you are.
- The Non-Native Speaker: A tool like this can be a huge weight off your shoulders, ensuring your communication is always clear and professional.
- The Email-Hater: If writing emails feels like a chore you constantly put off, this can help you break through that writer’s block and just get it done.
Some purists in the industry might argue that AI is a crutch that weakens our communication skills. I see it differently. I'd argue that a well-prompted AI draft that is then polished by a thoughtful human is far better than a rushed, typo-riddled email sent at midnight out of desperation. It’s not about replacing thought; it’s about streamlining the execution.
My Final, Unfiltered Thoughts on MailFast
So, where do I land on MailFast? It’s not a magic wand that will make your inbox disappear. But it is an exceptionally good assistant. Going back to my original analogy, it didn't extinguish my inbox dumpster fire, but it did give me a much better, high-tech fire hose to manage it.
It’s a powerful tool that, when used correctly, can genuinely save you hours of time and mental energy every single week. The key is to see it as a collaborator, not a replacement for your own brain. Use it to build the foundation, but always be the one to add the finishing touches. For me, it’s earned a permanent spot in my digital toolbox.
Frequently Asked Questions about MailFast
- 1. Can MailFast write in different tones, like casual or formal?
- Yes. While not an explicit feature you toggle, you can guide the tone through your prompts. If you write a prompt like, “Write a chill email to my buddy Dave,” it will produce a much more casual response than a prompt for a formal business proposal.
- 2. Is my data secure when using MailFast?
- This is a major concern with any AI tool. While I haven't done a deep security audit, most reputable SaaS companies like this use industry-standard encryption and privacy policies. As a rule of thumb, I avoid putting highly sensitive or proprietary information into any third-party AI for now. It’s best for day-to-day business communications.
- 3. Does MailFast integrate directly with Gmail or Outlook?
- The information suggests it's a web app or potentially a browser extension. Most tools in this space aim for seamless integration with major email clients to be truly useful. The “easy-to-use” description points towards a workflow that doesn’t require constantly switching tabs, likely through an extension.
- 4. Is the $9/month Professional plan actually worth it?
- If you send more than 10 important emails a month and value your time, I'd say yes. The time you save on drafting and replying to emails can quickly surpass the $9 cost, making it a positive return on investment for your productivity.
- 5. Can I cancel my subscription at any time?
- Typically, modern subscription services like MailFast allow for easy cancellation from your account settings. You'd likely retain access for the remainder of your paid billing period.
If you're feeling the email burn, I'd say give MailFast's free plan a shot. You've got nothing to lose but the ten minutes you'll save on your next handful of emails. And that, my friends, is a pretty good deal.
