Read on Trustpilot →Have been using winnr for about 3 months now with 5% reply rates on seveeral campaigns. Really happy with the results so far
Read on Trustpilot →I was using various other custom infra providers but really struggled with how often they mailboxes would disconnect from my sequencer. I constantly had to login and reconnect my mailboxes. With winnr I don't have that problem and their deliverability is great with great support, at a lower price point than all the similar providers I've used.
Read on Trustpilot →I get just as good of deliverability with winnr as I do with Google Workspace accounts that cost 3-4x more. Winnr mailboxes perform just as well when sending to Google workspace and they do decent at Microsoft, just as good as I do with Google Workspace accounts sending to microsoft, for a fraction of the cost. Its a no brainer for scaling an diversifying to use a high quality private infra provider like winnr.
Read on Trustpilot →I have a lot of software, and Winnr is by far both the best result and customer service I have experienced.
The team is incredibly responsive to help, builds solutions and new features to solve our business problems quickly.
The actual software has increased our email open rates by a minimum of 25%, if not much higher!
