Heymarket

• Messages are billed separately in credits: the page shows $0.03 per credit and one SMS segment is 1 credit, MMS 2 and RCS rich media 3.
• Prices shown are billed annually with a 2-user minimum; the page says monthly billing is available but does not show its price.
• Group messaging, lists, campaigns and automations are not on Standard, and API access needs Pro.
• A $10 per month per campaign charge covers 10DLC registration and compliance, and RCS rich media is annual-plans only.

MessageMedia (now Sinch Engage)

• Every plan is a monthly SMS allowance with a fixed price, so the cost climbs steeply with volume: $249 a month at 10,000 messages and $799 at 40,000.
• The pricing page shows only monthly prices; it offers a 16% saving for annual payment but does not display the yearly figures.
• The inbox, role-based access and mobile app start at the $249 Conversations plan, and the Basics plan has a single user.
• MessageMedia is being rebranded to Sinch Engage, and the old messagemedia.com address now redirects to sinch.com/engage.
