Recently, SendGrid discontinued their free tier which I previously used with my store.
In researching viable options with a free tier that was generous enough for real world use, I found SMTP2Go and am quite pleased with the service. It was easy to setup and worked immediately by following their guide although dated... the instructions still work for newer versions of Opencart. See here. https://www.smtp2go.com/setupguide/opencart/
For those looking to replace SendGrid or similar services, SMTP2Go is a solid replacement.
I have been using Zoho Mail for free for a few years. Yet another good alternative.tdaubss wrote: ↑
