Email hosting for small business — Why email is the highest-support product on your shelf
Nobody phones about a web page that loaded slightly slowly; everybody phones about an invoice that never arrived, and they phone the same afternoon.
Straight answer first
Price client email as its own product rather than folding it into a hosting retainer: it produces more tickets per pound than anything else you resell, it consumes your disk allotment permanently, and a bounce message is the most common way a client discovers who your supplier is.
The sections below cover the four ticket types that make up almost all of it, the deliverability work that has to be done once per client domain, what mailboxes do to a reseller allotment over three years, and the two exits for a client whose mail has outgrown their hosting.

Every reseller underestimates this. Websites are static in the sense that matters — they sit there and are looked at. Mailboxes are used all day by people who are not technical, on devices they change, from networks they do not control, with consequences that are immediate and financial when something goes wrong.
The relevant figures: mailboxes on the client's own domain come with hosting plans; standalone Email Hosting is $2.99/mo for up to 10 mailboxes at 10 GB each; Business Standard at $19.99/mo includes a hundred mailboxes. Underneath all of it, MailChannels carries outbound mail and SPF, DKIM and DMARC are set up.
The four tickets that make up nearly all of it
New device, nothing syncs. The client changed phones. Send the IMAP, POP and SMTP settings as a screenshot in your onboarding pack and this drops sharply, because the failure is almost always a mistyped password or a client app defaulting to POP and quietly removing mail from the server.
Somebody left. A staff change means an address to forward, an autoresponder to set, and a mailbox somebody still wants access to. Aliases, forwarders, autoresponders and a catch-all are all available per account, and doing this with a forwarder rather than a new mailbox keeps both your time and your disk allotment intact.
It went to spam. Occasionally yours, usually theirs — a recipient's filter, a shared IP reputation, or an address that has never been authenticated. This is the ticket that takes the longest and produces the least gratitude, which is exactly why the authentication work belongs at onboarding rather than at incident time.
The mailbox is full. Mail grows and nobody deletes anything. This is the one that costs you money rather than time, because it consumes disk you are paying for on your own reseller allotment.
Deliverability is a one-off job per client
SPF, DKIM and DMARC are set up on the platform, and outbound mail is carried by MailChannels. That covers the sending side properly. What it cannot cover is the part that lives in the client's own decisions: a marketing tool sending as their domain without being authorised, a contact form sending as a random address, or an old third-party sender still in the SPF record from a supplier they left in 2021.
Do that audit once, at onboarding, and write down what you found. Which systems send as this domain? Are they all authorised? Is the DMARC policy set to something meaningful, and does the client understand what happens if it is tightened? Fifteen minutes at the start prevents the hardest ticket type you will ever handle.
The reason this matters more to a reseller than to an end user is exposure. When a message bounces, the rejection text contains hostnames and IP addresses. A curious client pastes that into a search engine, and suddenly they are reading about a company they have never paid. Handling deliverability well is the cheapest way to keep that conversation from happening.
What mailboxes do to your allotment over three years
Reseller 1 carries 30 GB of NVMe across up to 100 accounts. A brochure website is perhaps 200 MB and stays there. A working mailbox at a trading business grows by a gigabyte or two a year and never shrinks, because attachments accumulate and nobody has ever willingly run a clear-out.
So the arithmetic that catches resellers out is: twenty clients with three mailboxes each, after three years, is most of your disk. The websites are a rounding error. Set mailbox quotas in the package you build, review the aggregate quarterly, and know the step to Reseller 2 at $29.99/mo with 60 GB is a line change on your own account.
Aliases and forwarders are the free lever here. A department address that forwards to two people costs nothing; three separate mailboxes for the same three humans costs disk permanently. Teach the client the difference once and you will both benefit.
Two exits when mail outgrows the hosting
The first is the standalone Email Hosting plan at $2.99/mo — up to 10 mailboxes with 10 GB each, webmail plus IMAP, POP and SMTP, spam and virus filtering, shared calendars and contacts, and a free migration of the old mail. This is the right answer when the client's website goes somewhere else, or does not exist, but the professional address still matters.
The second is a bigger hosting shelf. Business Standard at $19.99/mo comes with a hundred mailboxes alongside its 500 GB of disk, which is a sensible landing place for a firm that has grown past the point where mailbox count is a constraint you should be managing by hand.
In both cases the mechanics are the same and worth telling the client plainly: the MX records move in a few minutes and the website never notices. An IMAP migration copies folders and history into the new mailboxes, the address carries on working throughout, and DNS only changes once the copy has been checked. Fear of losing email is what keeps clients on arrangements they have outgrown; removing that fear is a sale, not a favour.
The product most likely to name your supplier
Bounce messages, mail headers and webmail URLs are the three places where a supply chain leaks. Private nameservers, your own branding and a mail setup that simply works are what keep a client's attention on you rather than on a hostname they found in a rejection notice.
Spam and virus filtering is fitted to every mailbox and outbound mail is carried for you, so the failure modes that would expose the chain are the ones least likely to happen.
- Aliases and forwarders instead of extra mailboxes
- SPF, DKIM and DMARC configured per domain
- Free migration of the client's old mail
- Mailbox quotas you set per package
Why Hosting Seller
On every plan, as standard
Filtering fitted to every mailbox
Spam and viruses are removed before the client sees them, which is the difference between a mail product and a mail liability.
Authentication handled underneath
SPF, DKIM and DMARC are set up and MailChannels carries outbound mail, so the hardest tickets are the least likely.
Free migration of old mail
An IMAP copy brings folders and history across, and the client's address keeps working the whole way through.
Forwarders that cost no disk
Department and ex-staff addresses can be handled without permanently consuming your reseller allotment.
A standalone plan when the site moves
Email Hosting at $2.99/mo covers up to 10 mailboxes at 10 GB each for clients whose website lives elsewhere.
Round-the-clock cover
Mail problems do not wait for office hours, and neither does the desk standing behind yours.
First Steps
From choosing to live
- 1
Audit the client's senders at onboarding
List every system that sends as their domain, check each is authorised, and write down what you found — fifteen minutes that prevents the worst ticket type.
- 2
Send mail settings as screenshots
IMAP, POP and SMTP details in image form, in the welcome pack, before the first device is set up.
- 3
Set mailbox quotas in the package
Mail is the only thing on a hosting account that grows forever, so the quota is what protects your own allotment.
- 4
Teach forwarders over mailboxes once
Department addresses and ex-staff routing cost nothing as forwarders and cost disk permanently as mailboxes.

Things people ask us all the time
Should I charge separately for client mailboxes?
Yes, and visibly. Mail is the highest-contact product on your shelf and the only one that consumes your disk allotment permanently, so folding it silently into a hosting retainer means the most expensive thing you supply is the one the client thinks is free. A per-mailbox line, however small, also gives you a natural mechanism for the conversation about forwarders versus mailboxes.
A client's mail is going to spam at one recipient. Where do I start?
With the headers of the actual rejection, not with the server. Confirm the sending system is authorised in the client's SPF record, check DKIM is signing, then look at whether the recipient's own filter is the cause — it very often is. Most of these end with the recipient's IT adding an allow entry, which is a phone call your client makes and you cannot. Set that expectation early or the ticket runs for a fortnight.
What do I tell a client who reads a supplier's hostname in a bounce message?
The plain version: the platform is operated by IGI Security Services Ltd, registered in England and Wales, and you are their point of contact for everything on it. Clients ask this out of curiosity rather than suspicion, and a straight answer given immediately closes it. What does not work is evasion, because the information is already in front of them.
Can I move a client's mail without breaking their website?
Yes — they are separate records. The MX records point wherever the mail lives and the A record points wherever the site lives, so moving one leaves the other untouched. Run the IMAP copy first, check it, then change MX. The address carries on working throughout, and the only visible effect is new mail arriving in the new place.
How many mailboxes can I sensibly allow per client account?
Fewer than the client will ask for, and quota'd. Standalone Email Hosting carries up to 10 mailboxes at 10 GB each, which is a useful yardstick for what a small firm actually needs. Beyond that, Business Standard at $19.99/mo comes with a hundred. Between those two points, forwarders do most of the work people think they need mailboxes for.
