Frequently Asked Questions

Everything you need to know about multiple domain email hosting

What exactly is multiple domain email hosting?
Multiple domain email hosting allows you to manage and send/receive emails from several unique domain names under a single account. With Attachmall, you can add unlimited domains, create separate mailboxes for each (e.g., hello@brand1.com, support@brand2.com), and control everything from one dashboard — completely free on the Free plan or with affordable upgrades.
Is Attachmall really free for multiple domains and unlimited mailboxes?
Yes, our Free Forever plan gives you 15GB storage, 5 email accounts, 1 domain, and full features. For unlimited domains and unlimited mailboxes, you can upgrade to any paid plan starting at $4.95/mo. Still extremely affordable with no per-user fees. All plans include unlimited email accounts per domain.
How do I add my own domains to Attachmall?
After signing up, navigate to "Domains" → "Add Domain". Enter your domain name, then update your DNS records (MX, TXT, CNAME) as shown in our step-by-step wizard. Verification usually takes a few minutes. Once verified, you can instantly create email addresses on that domain. You can repeat this for unlimited domains on paid plans.
Can I use third-party email clients like Outlook, Thunderbird or Apple Mail?
Absolutely. We provide full IMAP, POP3, SMTP, CalDAV, and CardDAV support. Just grab the server settings from your dashboard and configure any client. Enjoy seamless sync across devices. All protocols are included in every plan.
Is there any storage or sending limit?
Each plan includes generous storage (15GB on Free, up to 200GB+ on Enterprise). Daily sending limits are business-friendly (up to 1000 emails/day on higher plans). No hidden overage fees. You can always upgrade storage or contact sales for custom needs.
