You aren’t going to get anything good that is free with a custom domain. I use both google workspace and ms365. I’d you like using office, outlook etc. I’d suggest Microsoft. Answer from mark-bradley on reddit.com

r/smallbusiness on Reddit: I tested 10 free business email providers for my startup
July 29, 2025 -

I run a small digital agency and spent the last few weeks testing almost every free business email provider that supports custom domains — Zoho, Titan, ProtonMail, Migadu, you name it.

Here’s what I found (based on real-world use, not just feature pages):

What I Tested:

  • Setup time

  • Inbox deliverability

  • Custom domain integration

  • Mobile + desktop experience

  • Storage & spam handling

My Shortlist for 2025:

1. Zoho Mail – Best for small teams, clean UI, free forever
2. Titan Mail – Great if bundled with Hostinger or Namecheap
3. ProtonMail – Secure but limited free plan (no domain support)
4. Migadu – Developer-friendly, generous free tier
5. Gmail Alias Hack – Forwarding works, but looks unprofessional

Full Writeup (with pros/cons & screenshots):

I documented everything in this post for founders and freelancers:
👉 Top 10 Free Business Email Services in 2025

Hope it helps anyone trying to set up professional email without spending ₹500+/mo. Happy to answer any questions or suggest alternatives if needed.

r/selfhosted on Reddit: Free or minimum cost business email without having a domain?
January 13, 2025 - Gmail apparently has a free business tier with no custom domain support, everybody uses @gmail.com addresses but there's some level of central organization and control, I think, as opposed to everyone just using personal accounts. ... Google. 6 bucks a month. ... 1- Netim hosting: if you buy a domain from them you will get free hosting including 1 x1GB email, if you want to upgrade, their prices still fine.

r/Entrepreneur on Reddit: Setting up a new business: What's the best free email and calendar account with custom domain?
January 9, 2022 -

Hello!

I am struggling to find what I need, and I am thinking that actually the service I am looking for does not exist for free.

I am setting up a business and am looking for a free email and calendar hosting service that allow me to also use my custom domain.

Above that, it would be nice to have the ability to use third-party apps like Gmail, Outlook or Mail (iOS), but mainly Gmail because that's where my personal email is.

I think this is a lot to ask for free and couldn't find a service yet that has all these things together. So far I came accross:

Hostinger: free, up to 100 accounts, but it seems to not have the calendar functionality. If anyone knows how to "solve" this, I would appreciate.

Zoho: free, up to 5 accounts, has email and calendar, but I can't connect it to third-party apps (correct me if I'm wrong).

Thanks! Would love to hear your inputs.

I have two Gmail accounts currently (one main, one throwaway). I have heard of ProtonMail for privacy/security minded folks. I don't want a third Gmail account, I want a domain name my future clients will recognize (though this isn't vital, they're very unlikely to be familiar with ProtonMail), and it needs to be free or low cost (I don't want to be spending $40+ a month on an email address).

I have a day job and we use Outlook there, so I'm familiar with Outlook's current layout. I use Apple devices at home.

r/smallbusiness on Reddit: New small business owner : what’s the cheapest reliable business email on my own domain?
October 24, 2025 -

Hi everyone—just started a small business and want to keep startup costs as low as possible while still looking professional with a domain-based email.​

I’m in the U.S. and open to free or ultra-low-cost options that support a custom domain.​

So far I’m looking at Zoho Mail’s free plan for up to 5 users on a custom domain, Namecheap Private Email at about $1/user/month, or using Cloudflare Email Routing to forward my domain email to an existing inbox.​

I can live with basic features since I am only one to use it now, but I care about deliverability and would like an easy upgrade path if I outgrow the free tier.​

Would you recommend one of these, or is there another budget-friendly provider that’s worked well for your small team in the U.S.?​

Thanks in advance for any advice!

I'm helping a friend with a small business, every time I look up "How to create a business email" the results show up with services I need to pay for.

Is there a way I can do it for free or use a regular Gmail account?

Any help is appreciated.

(Yes I already have a website being set up)

I know that Zoho Mail is free, but I’ve heard a lot of negative reviews about its reliability and deliverability.

I wanted to know if there are any real free email platforms (apart from Zoho Mail) that are actually usable for a small business.

I am looking for free business email providers. Need suggestions (No Zoho Please) : r/smallbusiness
3 weeks ago - You will have to get your hands dirty to get it up and running with your own domain as it’s no frills. Apart from that I would recommend Microsoft Exchange Online Plan 1 from m365 as it comes in at roughly £3 a month. Remember when a product is free your data becomes the product the company ...

r/Emailmarketing on Reddit: What are the best free email marketing tools for small businesses?
January 16, 2025 -

I want a free reliable software that will basically automate my email marketing. I have this idea where i want the first 20-500 people who sign up their email to receive an exclusive offer but people that sign up after that number won't receive it. It just stops sending that email after the first 20-500. I'm only really planning to send 1-2 a month. I want to be able to create fun, colorful, interactive email where if you push a button out comes something. Is there a way i can do that? Any help would be great.
