Respondable | Boomerang for Gmail

What is Respondable | Boomerang for Gmail?
Respondable is an email assistant built into Boomerang for Gmail that scores drafts as you type. It predicts how likely a message is to get a reply and explains which factors drive that score, drawing on patterns from millions of sent emails. The tool surfaces tips on tone, including politeness, positivity, and subjectivity, so you can adjust wording before hitting send.
Most Gmail users guess at tone and hope for a response. Respondable gives live feedback inside the compose window instead of waiting for silence. That makes it especially useful for outreach to clients, follow-ups with your manager, and any thread where a missed reply costs time.
Sales reps, recruiters, and anyone living in Gmail who needs higher reply rates are the core audience. Respondable ships as part of the Boomerang extension, which also covers send-later, reminders, and inbox pause. Boomerang reports more than 1 million businesses on the platform and SOC 2 Type 2 certification on its main site.
PowerDMARC

What is PowerDMARC?
PowerDMARC monitors and enforces DMARC, SPF, DKIM, MTA-STS, and BIMI records from a cloud dashboard. Teams publish authentication policies, review aggregate and forensic reports, and move domains from p=none toward quarantine or reject to block spoofing and phishing. The platform also ships free public checkers for DMARC, SPF, DKIM, and BIMI lookups.
Generic email security suites spread across many products. PowerDMARC centers on authentication enforcement with hosted SPF flattening, one-click DNS publishing, a live threat map, and an in-dashboard DMARC AI Agent for troubleshooting SPF permerrors and deliverability drops. MSP and MSSP partners get a white-label multi-tenant console to resell under their own brand.
IT admins, MSPs, and marketing teams at mid-size and enterprise organizations use PowerDMARC to meet Google and Yahoo sender requirements, protect domain reputation, and monitor blacklist and header health. Pricing starts with a free personal-domain tier and scales to custom enterprise quotes.
