Overview
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.
StayFi
StayFi helps you take control of your guest data by replacing standard home Wi-Fi with a branded splash page. Instead of only knowing the person who booked the stay, you can now collect names and email addresses from every guest who connects to the internet. This allows you to build a massive marketing database of travelers who have already experienced your properties.
You can use this data to send automated email and SMS campaigns that encourage guests to book directly with you next time, bypassing expensive OTA fees. The platform also includes tools for managing your brand across multiple properties and monitoring Wi-Fi health in real-time. It is designed specifically for vacation rental managers and Airbnb hosts who want to grow their independent brand and increase their bottom line.
