Interspire Email Marketer vs MailWizz (2026): which should you pick?

Pick Interspire Email Marketer if

• Fits if you have someone to run a Linux server and want one payment
• Works for teams that want white-labelling and unlimited contacts

Look elsewhere if

• Not for you if you want to try it free, as nothing is listed
• Skip it if you don't have someone to run PHP and MySQL
• Watch out: you supply your own SMTP or email provider, and deliverability setup is not standard
• Watch out: updates and support last a year, then renewal starts at 25% of the price
• Tight if you need more than 5 user accounts, which needs a custom licence

Pick MailWizz if

• Fits if you can host it and want to avoid per-subscriber fees
• Works for agencies that want to resell it, using the Extended licence

Look elsewhere if

• Not for you if you want to try it free, as there is no trial
• Skip it if you don't want to run a server, since the licence doesn't include servers, sending or deliverability
• Watch out: annual subscriptions go offline after a 5-day grace period if they lapse
• Watch out: each licence includes only 1 month of premium support
• Not for you if you want to charge customers on the Regular licence, which is personal use only

Interspire Email Marketer

• It runs on your own Linux server with PHP 8.4 and MySQL 8.0+ or MariaDB 10.5+; the vendor says you need someone comfortable administering them.
• The price does not include sending: you supply an SMTP server or email provider, and deliverability setup is not part of the standard license.
• Updates and support last one year; renewal starts at 25% of the license price.
• The Self-Service License includes 5 user accounts; larger or multi-team deployments need a custom license.

MailWizz

• You host it yourself; the license does not include servers, sending or deliverability, and the vendor's hosted MailWizz is a separate service.
• Subscriptions last one year. If one lapses, the vendor says the application goes offline after a 5-day grace period, though the data stays untouched.
• Each license includes 1 month of premium support; longer support is sold separately.
• The Regular license is for personal use only; charging customers for access requires the Extended license.
