How Inboxroad pricing works
Inboxroad offers volume-based email pricing across three plans: SMTP, Email, and Email Pro, with selectable volume tiers ranging from 10K up to 1M+ emails per month (and scaling up to 300M+ upon contact). At the 100,000 emails per month level, pricing is shown in EUR starting at €68/month for SMTP, €248/month for Email, and €578/month for Email Pro. Exceeding volume limits incurs overage charges billed at the exact same CPM (cost per thousand) as the selected plan, and users can send 1,000 emails per month for free.
- Volume slider options shown: 10K, 50K, 100K, 250K, 500K, 750K, 1M, 1M+
- Free trial available: 1,000 emails free every month
