Question: Can you suggest a service that helps me get more emails delivered to inboxes and less to spam folders?

Unspam is a serious email deliverability and optimization service. It's got a spam checker, a deliverability test, and heatmap predictions to help you get your emails into the inbox. It also checks for blacklisting and supports several email authentication standards that can help keep your sender reputation high and engagement high.

Another contender is Mailivery, an AI-based email warmup service that uses real email interactions to improve your sender reputation and avoid the spam filter. It offers real-time analytics and lets you control sending behavior, so it's a good choice for sales teams trying to optimize email deliverability and get more emails into inboxes.

For managing email, hi.new is an interesting service that blocks spam and phishing attempts but lets legitimate contacts reach you. It's got a contact form system, disposable email and AI-based filtering technology to keep your inbox tidy and safe. That can help you tackle the problem of unwanted emails, which make up a big fraction of all emails.
