Say goodbye to cold, impersonal scheduling links. Use zcal to create beautiful, personalized booking pages that make a great first impression on your guests. It's 100% Free Forever 🔥!

If everyone agrees that scheduling links help save time, then why are they so universally unloved? Today most booking pages present nothing more than a name and a calendar, so as the person receiving the link, the process of booking a time can feel cold and transactional.

I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

  • SES emails not delivered to Gmail, but Gmail says successfully received
    You should check to see if the messages that are being sent contain any links that would be considered questionable/spammy. You can also try taking the content of one of the messages and checking it’s spam assassin score ( https://spamcheck.postmarkapp.com ). Source: over 2 years ago
  • When I do warming up, should I use the actual templates I would sent to the cutomers ?
    Build a clean email that passes a spam check with flying colors (https://spamcheck.postmarkapp.com/) then use a warmup service like lemwarm, inboxally or neverspam as mentioned in the other comments. Source: almost 3 years ago

  • Cal.com: The Open-Source Calendly Alternative
    >ended up just switching over to https://zcal.co and it has been great so far Wait wait wait. It can sync my Google and Outlook calendars into a single scheduling service, and they're not charging me anything? What's the catch here? - Source: Hacker News / over 1 year ago
  • Cal.com: The Open-Source Calendly Alternative
    I've poked around a while ago at some Calendly alternatives (specifically was looking for something that was cheaper than Calendly with most of the basic features). I tried using cal.com for a bit but ended up just switching over to https://zcal.co. All these scheduling apps end up trying to do too much and always seem to end up a bit clunky. - Source: Hacker News / over 1 year ago
