See Email Hosting PlansWhat Every Mailbox Tier Includes
Whether you need three mailboxes or three hundred, the underlying platform is the same reliable, secure mail infrastructure — only the scale changes.
Your Own Domain
Mailboxes are provisioned on your own domain — [email protected] — for a professional identity in every message you send.
Spam & Virus Filtering
Inbound mail is filtered before it reaches the mailbox, keeping inboxes clean whether you run one mailbox or a few hundred.
Webmail + IMAP/POP/SMTP
Access mail from a browser or connect Outlook, Apple Mail, Gmail app or any standard mail client via IMAP, POP or SMTP.
GST Invoicing
Every plan is billed in INR with GST-compliant invoices, so your mailbox subscription slots straight into business accounting.
Mumbai & Delhi Placement
Mail infrastructure is served from Indian data centers, keeping send/receive latency low for domestic teams and clients.
Tiered Mailbox Scaling
Add mailboxes and storage as your team grows — from a founder's inbox to department-wide distribution lists.
Small Business Mailboxes vs. Enterprise-Scale Needs
A five-person consultancy and a two-hundred-person enterprise both need reliable, professional email — but the requirements diverge quickly past a certain size. A small business typically needs a handful of mailboxes, each used by one person, with enough storage to keep years of client correspondence searchable. What matters most at this scale is that setup is fast, the price is predictable, and support is responsive when someone can't send an invoice on deadline day.
Enterprise-scale email needs look different. There are more mailboxes to provision and de-provision as staff join and leave, department-level distribution lists and shared mailboxes, higher per-user storage expectations, and often a requirement for admin-level visibility into mailbox usage across the organisation. Billing also tends to be consolidated — one GST invoice covering every mailbox on the account rather than piecemeal purchases, which matters for finance teams doing monthly reconciliation.
Hoststack's Business Email plans, starting at ₹39/mo per mailbox, are built to flex across this range. You can start with three mailboxes for a founding team and add more as headcount grows, without migrating to a different platform or losing existing mail history. If you're launching a new company domain alongside your mailboxes, our domain registration service lets you register and configure DNS/MX records from the same account.
If your organisation's needs go beyond mailbox hosting — internal tools, a custom intranet, or an application server that email integrates with — our Linux VPS plans from ₹399/mo give you a dedicated environment to run those alongside your mail setup.
