What SocketLabs is
SocketLabs is an email delivery and analytics platform for sending, analyzing, and optimizing email. Customers can send through SMTP relay or the Injection API, with inbound email, delivery event webhooks, and templates available. Spotlight turns data from Mailgun, Bird, and SendGrid into performance insights and includes StreamMonitor, Guided Insights, StreamScore, and a sending overview. Its Rule Engine can deliver directly, relay through another provider, or split traffic among providers. Spotlight connects with SendGrid, Mailgun, and SparkPost; Amazon SES is listed as planned. Hurricane MTA provides an on-premises sending option. Core costs $39.95 a month after a first month billed at $0 and includes 40,000 emails monthly; extra messages cost $0.00130 each. Pro 100k costs $89.95 a month and includes 100,000 emails monthly, with a dedicated IP and $0.00110 overage.
