RampBenchInframail
Microsoft-backed inbox infrastructure with flat-rate pricing, for lead-gen agencies running many sending domains.
Inframail provisions inboxes on domains you own and writes the SPF, DKIM, and DMARC records as part of setup. Pricing is per plan rather than per inbox, with monthly sending volume as the limit. It includes domain purchasing, blacklist and deliverability monitoring, and connections to Instantly, Smartlead, and Woodpecker.
