Overview
SendForensics
SendForensics helps you solve the complex puzzle of email deliverability by analyzing your outgoing mail before you hit send. Instead of guessing why your emails land in spam, you get a detailed breakdown of content triggers, infrastructure health, and sender reputation. You can proactively identify issues with SPF, DKIM, and DMARC records while testing your content against global filtering systems in real-time.
The platform acts as a pre-flight check for your email campaigns, allowing you to optimize engagement by ensuring high placement rates. Whether you are managing a single brand or a high-volume agency, you can monitor your global sender reputation and receive alerts if your domain appears on blacklists. It integrates with your existing email service providers to provide a continuous layer of deliverability intelligence.
Email on Acid
Email on Acid helps you eliminate the guesswork of email marketing by previewing your campaigns across over 100 different email clients and devices. You can catch rendering issues, broken links, and accessibility problems before you hit send, ensuring every subscriber has a consistent experience. The platform automates the tedious manual testing process, allowing your team to deploy high-quality emails faster and with more confidence.
Beyond simple previews, you can optimize your inbox placement with deliverability tools that check your IP against blacklists and validate your SPF and DKIM records. Whether you are a solo developer or part of a large enterprise marketing team, the platform provides the technical insights needed to bypass spam filters and improve engagement. You can integrate these checks directly into your existing workflow to maintain brand standards across every communication.
