If you need to keep things entirely on your website or don’t want to integrate too many third part services, The Event Calendar is a satisfactory solution, provided you realise that many of the bells and whistles are premium services, though not necessary for a fully functional service.
If you are needing an all singing and dancing event management solution you are probably making some money from events. Naturally this comes at a cost – in terms of your time to set up the systems and managing each event and using either a third party service or a premium plugin. Remember too that linking with Paypal or Stripe involves processing fees and storing customer and transaction data.
We only recommend the paid tool for more advanced users. Also you should have a full blown email account set up on your domain and able to send via your “authorised” domain via a reputable mail provider (to avoid server mail ending up in spam).
If you want help to get set up, ping us a mail, but we can’t do this for nothing unless you qualify for our free support.
