Bulk ordering for 20-100+ inboxes
Email-based support
Shared infrastructure with some dedicated options

Mailreef Pricing

Mailreef sits in the mid-tier pricing range: $3-5/inbox/month for basic Google Workspace. No pre-warming included — users need separate warmup tools ($15-25/inbox extra). True all-in cost: $20-30/inbox/month.

Deliverability Performance

Mailreef deliverability tracks:

Reply rate: 2-3%
