How to: Development: Error: Could not instantiate mail function

Our hosting team is continually working to ensure that the newsletters from your online store are always successful. To make it, we have implemented extra checks and improvements to get a high reputation for your domain and deliverability, which means your emails will be delivered and seen.

  • For example, sending emails to domains like test.com, example.org and similar ones are blocked. Don’t use domains like these for test purposes because you can’t check these email :)
  • We also check that an email can be delivered based on the DNS records, and if this check fails, it is also blocked this email. This extra check helps us to fight against sending to domains where there are mistakes or mistyping, such as gmal.com (there's an omitted letter), hotmailcom (missed dot) and similar ones.

These types of errors can create message like shown below

Root causes

Sending emails to domains like test.com, example.org and similar ones

Don’t use domains like these for test purposes because you can’t check these email :) For test purposes we can recommend using the spam-check.glockapps.com, isnotspam.com, mail-tester.com, spamtest.smtp.bz and dkimvalidator.com or your real email address :)

Sending emails to domains with mistakes or mistyping

Sometimes email can’t be delivered based on the DNS records (MX, A), and if this check fails, we blocked this sending attempts. This extra check helps us to fight against sending to domains where there are mistakes or mistyping, such as gmal.com (there’s an omitted letter), hotmailcom (missed dot), and similar ones.

Conclusion

Use valid email addresses and all will fine 😀
