What it is
WarmupHero is an email warmup service that gradually increases sending volume to build an address’s reputation and reduce spam risk. It says setup takes one minute, works with all email service providers and runs automatically. The service exchanges warm-up messages with real people, sends personalized emails sequentially and keeps messages in conversation threads with automated replies. It opens warm-up emails, marks them important and moves them back to the inbox when they land in spam. Analytics show whether messages reach the inbox, spam or folders such as Promotions and Updates. Users can customize messages and add signatures containing images or links. Connections include the Office365 API and an SMTP/IMAP method for other business accounts. SmartReach.io users generate an API key before connecting an email account. WarmupHero is available as a web service and extension, with spam monitoring listed. Its free SmartReach.io plan costs nothing. The privacy policy says it does not access, read or delete users’ emails, while it may process information supplied about recipients and customers.
