Koltrix vs Zoho Mail

What Zoho Mail is

Zoho Mail is custom-domain business email at a low price, part of a very large suite that covers CRM, projects, books and dozens of other applications. If you want one vendor for the whole back office at the lowest possible price, that is the pitch.

Choose Zoho Mail if…

• Price per mailbox is your main constraint.
• You want the rest of the Zoho suite — CRM, Books, Projects — from the same vendor.
• You need IMAP, POP and ActiveSync for existing mail clients today.
• You need mailboxes hosted in a specific region Zoho offers and we do not.

Choose Koltrix if…

• Your product sends email. Zoho Mail is a mailbox host; the transactional side is a separate product and a separate integration.
• You want the inbox and the sending API to share one address book, one API key and one bill.
• You want agents that screen cold pitches and track what was promised, not just folders and filters.
• You would rather set up SPF, DKIM and DMARC once, with a wizard that checks them live, than read a support article.
