Show HN: Doubletick for Gmail – Email Open Tracking Extension
- sscarduzio 5y agoI'm afraid to use this for work emails because my normal emails already too often get caught in customers' shitty corporate antispam filters :(
- karanxlr 5y agoDon't worry Doubletick won't affect your email reputation, Spam filters usually caught into filters due to content in email body.
