WarmupIP
No Spam. Just Inbox.·warmupip.com
WarmupIP is an email deliverability platform that warms up domains, IPs, and mailboxes for high-volume senders using a network of seed mailboxes that generate real engagement such as opens, clicks and replies. It provides managed SMTP/ESP routing across providers like Amazon SES, Google Workspace, SparkPost, Mailgun and SendGrid, plus direct API integrations with Klaviyo, Mailchimp and GoHighLevel that let users warm domains without DNS changes. The platform also offers deliverability consulting, free diagnostic tools (inbox placement tests, SPF/DKIM/DMARC checkers, subject line analyzers) and real-time reporting on opens, clicks, spam rates and inbox placement. It is aimed at regulated and high-volume senders such as fintech, BFSI, insurance, healthcare, affiliate marketers and B2B lead-generation companies.

Pricing
The pricing pages present overlapping 'Starter/Growth/Scale' names for two different pricing tracks (ESP-routed sending vs. B2B warmup credits) with different prices under each name. A Monthly/One-Time toggle affects the Individual plan price ($199/mo vs $80 one-time); custom quote-based pricing is offered for very high-volume senders (50K-5M+ emails/day) via consultation.
