Group domains by a curated dimension.

POST 

/dev/v1/sender/domains/breakdown/:dimension

Returns one row per group of the chosen :dimension, aggregating only the caller’s enabledColumns to the single value the FE shows: a per-column count for categorical columns (unverified / Sending / None / Blocklisted / Inactive / Invalid), the average per verified root for engagement columns, sums for subdomains / alerts / total DMARC volume, and the volume-weighted DMARC compliance rate. Aggregates respect the same filter and advancedFilterConditions as composite/search and the fromDate/toDate range. Platform scope only — other sources receive 403.
