We work very hard to ensure that our deliverability rates remain high. Still, there are certain user behaviors that can get emails routed to the Spam folder.
Here’s what we recommend:
Keep your emails short and informal, paste your templates as an email you’ve written before.
Make sure you have a fully completed email signature with a physical address.
Use Google or Outlook to send your emails, or set up an SMTP to deliver messages through your own servers.
