Overview
SocketLabs is an email delivery platform for businesses that send at volume. You send through SMTP or its HTTP injection API, manage subaccounts and IP pools, and read deliverability through reporting tools: StreamScore, a color-coded reputation score built from more than 35 data points, and longer performance history than most competitors at the same price.
Core costs $39.95 a month for 40,000 emails (first month free) with ticket and chat support. Pro starts at $89.95 for 100,000 emails and adds a dedicated IP, StreamScore Pro, 30 days of detailed insight and 180 days of performance history, plus priority support. Enterprise is custom for 1 million+ emails and can add Rule Engine, which routes or splits traffic across several third-party providers.
Its Spotlight product analyzes webhook data from SendGrid, Mailgun and Bird, so teams can use SocketLabs reporting even for mail sent elsewhere. SocketLabs lists SOC II and GDPR/CCPA compliance.
