Configure custom properties and segments in Sendgrid

[TylerMatteo]

Configure necessary custom fields and segments in SendGrid for production and staging environments.

For staging and production environments, create the following custom fields, using the "number" custom field type

• [x] One for each of the 59 community districts
• [x] One for "citywide"
• [x] One to track whether or not the user has confirmed their subscriptions

Custom field naming convention

• Naming convention for CD fields should follow this pattern zap_<environment>_<CD identifier>. CD identifier should use ZAP CD IDs which ZAP Search already has a copy of here - look at the first item in each of the nested arrays (K01, K02, etc). For example, the field for K01 has already been created for staging:
• Naming for "citywide" field should be zap_<environment>_CW
• Naming for "confirmed" field should be zap_<environment>_confirmed

Note you should create 122 custom properties total

For staging and production environments, configure the following segments

• [x] One for each of the 59 community districts
• [x] One for "citywide"

Note you should have 120 segments total

Segment naming conventions

• Follow pattern zap-<environment>-<CD identifier>. For example, zap-staging-K01. For citywide segments, use CW for identifier.
• Segments should be associated with the Lists for their environments - (zap-subscribers-staging and zap-subscribers-production)
• Each segment should have two conditions
  • The custom field for the corresponding identifier is 1
  • The "confirmed" custom field for the corresponding environment is 1
