Some apps - especially CRMs - require an email address when creating a record, however, there are some situations where you might not have one. Use this zap to generate a random dummy email address to save.
This zap uses a "Formatter->Number->Spreadsheet-Style Formula" step to create a random number between 100000 and 999999. This ensures that the output will always be a 6 digit-long string, and is very likely to unique.
This can then be combined with something like "@email.com" to give you a dummy email address. You can save this directly to your CRM, but in our example we're sending it to ourselves in an email.
