If your agency or MSP runs client hosting through Hostinger's cPanel Reseller Hosting plan, the business model behind that plan is being switched off. Hostinger stopped accepting renewals for cPanel Reseller plans on October 1, 2026, and every remaining plan shuts down for good by October 1, 2027. If you've been using that WHM login to hand each client their own cPanel account, including their own mailboxes on their own domain, you now have a deadline to decide what runs your clients' email next. Atriomail is built around exactly the piece Hostinger's replacement doesn't have: billing one client's mailboxes separately from another's, through WHMCS or Blesta, as the whole product rather than a side feature of a web host.

Hostinger's own recommended replacement, Agency Hosting, is not a drop-in swap for what you're losing. It's a genuinely different product, aimed at a different job. Here's exactly what the discontinuation notice says, what Agency Hosting does and doesn't include, and how the per-client email billing you're about to lose looks on Atriomail instead.

Point Details
cPanel Reseller Hosting stopped renewing October 1, 2026 Every remaining plan shuts down by October 1, 2027 at the latest, and the page that used to sell it now returns a 404 (hostinger.com, checked October 2026).
The replacement, Agency Hosting, has no WHM, no cPanel packages and no billing software Hostinger's own product pages don't mention any of the three; a client book can't be split into separately billed accounts the way the old plan allowed.
Atriomail is $1.39 per mailbox with a WHMCS and Blesta module built for exactly this 15 GB included, no contract, and the WHMCS (v3.1.1) and Blesta (v2.1.0) modules put each client's mailboxes on their own invoice when they order.
Moving mail off a retiring plan doesn't have to start every mailbox empty Atriomail's free built-in IMAP migration signs in to the old mailbox first, copies folders and dates, and can run as a bulk job across many accounts from the same old server.

Work out your 200-mailbox book before the 2027 deadline arrives. Atriomail charges $1.39 per mailbox with 15 GB included, billed monthly with no contract and no minimum. Creating an account costs nothing and needs no card; mailboxes are billed from the first one you create.

What's Actually Ending, and When

Hostinger announced the change in May 2026: cPanel Reseller plans stopped being sold, and since October 1, 2026, they can no longer be renewed either (hostinger.com's own "Hostinger cPanel Reseller Hosting Discontinuation" support article, checked October 2026). Auto-renewing plans with an expiry date before October 1, 2026 keep renewing for up to 12 months at an adjusted price, with no further renewals after that; plans without auto-renewal could still be renewed manually, but only until September 30, 2026, for up to 12 months at the same updated pricing. Either way, every plan is terminated on its own expiry date or October 1, 2027, whichever comes first, a date the notice states plainly can't be extended.

If a plan is cancelled before then, Hostinger says you'll get a refund for the unused portion, or credit toward an Agency Hosting plan instead. What the notice doesn't cover is the mail itself: as of this run, Hostinger's own reseller-hosting page returns a 404, and the official discontinuation notice names only the recommended next step, Agency Hosting, without walking through what happens to the client mailboxes that were living under WHM.

The real question for a reseller isn't the exact date; it's what runs client email once the old plan is gone, and whether the replacement can do the one job the old plan did. For a book of any size, that's a reminder that planning around service interruptions has to include the platform itself, not just the mail flowing through it.

Planning to move 50 or more mailboxes off a retiring plan? Atriomail's IMAP migration tool tests each mailbox's sign-in before it starts and can run as a dry run first. For a book that size, plan the cutover with us before you commit to a date.

Agency Hosting Has No WHM, No Packages and No Per-Client Billing

What the old plan actually gave you was WHM: a reseller-level control panel where every cPanel account you created came from a package, cPanel's own term for a bundle of resources, disk quota, bandwidth, and a "Max Email Accounts" setting that could be set to a specific number per client or left unlimited (standard cPanel/WHM account-package behavior, documented across cPanel's own and third-party hosting knowledge bases, checked October 2026). That's the mechanism that let you sell client A ten mailboxes and client B two hundred from the same reseller account, each capped on paper even though Hostinger itself sent you a single invoice.

Agency Hosting doesn't have any of that. Hostinger's own page describes three plans (Startup, Professional and Growth); the Startup tier runs $29/month on an introductory rate requiring a 24-month term, renewing at $49/month, with up to 100 websites and 300 GB of NVMe storage shared across the account (hostinger.com/agency-hosting, checked October 2026). Email is bundled as "10 mailboxes per website, free for 1 year"; nothing on the page mentions WHM, cPanel or any billing or invoicing feature for individual clients, and there's no package system to cap one client's mailboxes differently from another's or turn either into a separate recurring charge.

Atriomail's WHMCS module (version 3.1.1, built for WHMCS 9) and Blesta module (version 2.1.0, for Blesta 6.0 and later) do the job WHM packages used to do, but as billing rather than just provisioning: when a client orders, the module creates their own Atriomail domain and, if it clears the standard security check during the order, their first mailbox, then lets them add mailboxes, change passwords and manage aliases from their own client area, billed as recurring charges on their own invoice at whatever price you've set. Moving 20 or 200 client domains off a retiring Hostinger plan is exactly the situation multi-client email management for agencies is written for, and it's also where a documented client support process matters, since you're changing the plumbing under many accounts at once.

Everything Comes Wrapped in a 24-Month Commitment

There's a second change buried in that pricing, easy to miss if you're focused on the WHM gap: Agency Hosting's advertised rate only holds if you commit to a 24-month term. Hostinger's own page lists the Startup plan at $29/month on that basis, renewing at $49/month once the term ends (hostinger.com/agency-hosting, checked October 2026). The old cPanel Reseller plans billed on whatever cycle you'd originally chosen; locking your entire replacement hosting relationship into a two-year contract while you're also rebuilding how you bill clients for mailboxes is a second decision riding on the first one, not a detail you can defer.

It's also worth naming what isn't published: Hostinger's own pages don't say what a mailbox costs once that first free year per website ends, so a reseller budgeting a client book past year one has no number to work from.

Atriomail doesn't ask for a term commitment on either side: billing is monthly, there's no minimum mailbox count, and the $1.39-per-mailbox price doesn't change based on how long you've been a customer or how many months you prepay. You can see how that per-mailbox number turns into your own retail price, and how that pricing flexes as a book grows, before moving a single client.

What Happens to the Mailboxes Already on Your Reseller Account

Hostinger's discontinuation notice covers migration logistics, just not email specifically. It states plainly that "cron jobs, DNS records, custom SSL configurations, or FTP accounts are not migrated and must be recreated manually" when a plan moves to its replacement (hostinger.com's discontinuation notice, checked October 2026). Mail isn't named on that list at all, which in practice means no confirmed, automated path exists for carrying existing client mailboxes from a cPanel Reseller account into Agency Hosting. The safest assumption is that mail, like DNS and SSL, is on you to move by hand, one account at a time.

That's the same job whether you're leaving Hostinger for Agency Hosting or for somewhere else entirely, and it's where the free year of included mailboxes creates its own pressure: the clock on worrying about year-two pricing doesn't start until year two, but the clock on the underlying plan being usable at all ends October 1, 2027 regardless.

Atriomail's IMAP migration is built into the panel at no charge and works with exactly the kind of mail a cPanel Reseller account produces: any server that allows IMAP sign-in with a password, including typical cPanel, Plesk or DirectAdmin hosting mail. For a single-mailbox job it tests the sign-in on both the old and new mailbox before it starts, so a wrong password shows up in seconds rather than mid-transfer, and it keeps the original folder structure and message dates instead of starting the new mailbox empty. Bulk jobs list many mailboxes from the same old server in one go and track how many completed or failed, though every account still needs its own password and a book of any real size should be planned with the team first rather than run unsupervised; the panel's own migration-status tracking documents the states a job moves through (scheduled, running, completed, failed or cancelled, checked October 2026). Re-pointing each domain's MX once the new mailbox is ready is its own step too: on a connected Cloudflare or Namecheap account, Atriomail can write the mail records directly into that zone; everywhere else, the domain's own DNS Setup dialog lists exactly what to copy at the host you're already using.

Hostinger vs Atriomail for Resellers

Put side by side, on the dimensions that matter to someone who was billing a client book through WHM, not running one mailbox:

Dimension Hostinger (Agency Hosting) Atriomail
Reseller-tier hosting product cPanel Reseller Hosting retired; no longer sold, page now 404s Per-client billing is the whole product, not a side tier
Per-client billing No WHM, no account packages, no billing software found WHMCS v3.1.1 and Blesta v2.1.0 modules bill each client's mailboxes on their own invoice
Mailboxes included 10 per website, free for year 1; price after year 1 not published $1.39/mailbox/month, 15 GB included, published, no contract
Contract / minimum Advertised Startup rate requires a 24-month term Monthly billing, no minimum mailbox count
White-label branding Unbranded client dashboards included on Agency plans Included from 50 paid mailboxes, else $50/month: your product name and favicon on your own hostname
Migrating existing mail into the new plan Not addressed; DNS, cron, SSL and FTP must be recreated by hand Built-in IMAP migration, free, with dry run, scheduling and bulk jobs
Support hours 24/7 live chat; priority support with faster response on Agency plans Business hours only
Refund / guarantee 30-day money-back guarantee No refund beyond duplicate or unauthorized charges within 7 days

The white-label, support and refund rows are worth sitting with rather than explaining away: Agency Hosting bundles an unbranded client dashboard at no extra fee, offers round-the-clock support with a stated priority response time on Agency plans, and backs the account with a 30-day money-back guarantee (hostinger.com, checked October 2026). Atriomail's white-label branding costs extra below 50 paid mailboxes, support runs during business hours only, and refunds are limited to duplicate or unauthorized charges reported within 7 days. If those three things matter more to you than per-client billing, this comparison alone shouldn't move you off Hostinger; the tradeoffs of hosting under your own name are covered further in this guide to white-label email for agencies and domain management and branding.

When Hostinger Makes Sense

Agency Hosting is a reasonable choice in a few situations:

  • You manage several clients' websites from one account but have never needed to bill their email separately, so losing WHM-level account separation isn't losing something you were using.
  • Ten free mailboxes per website, repeated across up to 100 sites, covers what your clients actually need without you needing a firm year-two price yet.
  • You want Hostinger's 24/7 priority support and 30-day money-back guarantee backing the whole account, and you're willing to trade per-client billing granularity for that.
  • You're not running client hosting through WHMCS, Blesta or any billing system that needs a per-client mailbox count to reconcile against, so the lack of WHM packages isn't a gap you'd ever hit, and day-to-day client email management for you means a handful of sites, not a book you bill separately.

If that's your actual book, moving to Agency Hosting before the 2027 deadline is a defensible call, and nothing here is an argument that it isn't.

Where Atriomail Fits

The decision changes once you were using WHM specifically to bill client email as its own line item, which is exactly the use case Agency Hosting doesn't replace. Take a 200-mailbox book, a realistic size for a reseller or MSP a few years into building a client list. Hostinger doesn't publish a per-mailbox wholesale price past the first free year on Agency Hosting, so there's no comparable monthly cost to compute on that side at all, for 200 mailboxes or any other number; the honest answer is that the product which used to make that number knowable is the one being shut down. At Atriomail's $1.39 per mailbox, 200 mailboxes cost $278 a month wholesale. Resold at $5 per mailbox, that's $1,000 a month in revenue and $722 a month in margin, before card fees, support time and any white-label fee. The number that matters more than the $722 is how it arrives: through the WHMCS or Blesta module, as 200 separately billed line items tied to 200 client accounts, the same job WHM packages used to do, on a platform where that's the core product rather than a feature a hosting company can retire out from under you.

If your Hostinger reseller account was never really about per-client billing, staying on Agency Hosting is reasonable. If it was, Atriomail's pricing and its WHMCS and Blesta modules were built for exactly that transition; create an account to look at the panel before moving a single client.

Run the 200-mailbox math before your Hostinger plan expires. At $1.39 per mailbox with 15 GB included, a book run through the WHMCS or Blesta module puts each client's mailboxes on their own invoice, not buried inside yours.

Frequently Asked Questions

What exactly stopped on October 1, 2026?

New renewals of Hostinger's cPanel Reseller Hosting plans. Existing plans with auto-renewal keep running for up to 12 months at an adjusted price with no further renewals after that; every plan, regardless of its own expiry date, is terminated by October 1, 2027 at the latest (hostinger.com, checked October 2026).

Does Agency Hosting replace what cPanel Reseller Hosting did?

Not for per-client billing. Hostinger's own Agency Hosting pages describe managing multiple client websites from one account, with no mention of WHM, cPanel account packages or any billing software that would let you charge each client separately for their own mailboxes (hostinger.com/agency-hosting, checked October 2026).

Can I bill Atriomail mailboxes separately for each client through WHMCS or Blesta?

Yes. The WHMCS module (version 3.1.1, for WHMCS 9) and the Blesta module (version 2.1.0, for Blesta 6.0 and later) both create the client's domain on order and the first mailbox once it clears the security check (in WHMCS, only during the order), then bill mailboxes and storage the client adds afterward as recurring charges on their own invoice, at your own prices.

What does the Atriomail white-label add-on cover?

It's included from 50 paid mailboxes, else $50 a month. Once our team sets up your hostname, the control panel on it carries your product name and favicon, and the help center pages carry your logo. Some layers stay neutral either way, including raw message headers, the webmail interior, payment pages and system emails.

Does Atriomail's migration tool move mail out of a Hostinger reseller account?

For typical cPanel-hosted mail, yes: the built-in tool works with any server that allows IMAP sign-in with a password, which covers standard cPanel, Plesk and DirectAdmin mail the way a cPanel Reseller account produces it. It doesn't cover Microsoft 365, Exchange Online or Outlook.com mailboxes; Microsoft no longer allows password sign-in over IMAP for those, so moving a Microsoft 365 tenant needs a different route. Talk to us before you quote that one.

What's the margin on a 200-mailbox book on Atriomail?

At $1.39 per mailbox, 200 mailboxes cost $278 a month wholesale. Resold at $5 per mailbox, that's $1,000 a month in revenue and $722 a month in margin, before card fees, support time and any white-label fee.
