Sendersy vs Unisender: an alternative without contact-based pricing
Unisender is a household name in the CIS market, but pricing grows with your contact list even if you rarely send. Sendersy charges for emails sent — not stored contacts — and includes SMTP, API and a visual editor.
Sendersy
Free 200 emails/mo → Basic and Pro flat plans. Pay for emails, contacts unlimited.
Unisender
