The monthly analytics report used a stale date window, so numbers didn't match the month shown. It now reports for the correct date range.
The monthly email report uses the reporting month's dates when calculating your marketing results. Its date window follows the brand's time zone, so the totals describe the month being reported rather than an earlier period. This helps your team review the same period when comparing the email with marketing analytics.
Open Marketing Analytics Settings to review whether monthly report emails are enabled and who receives them. Existing enabled reports use the corrected calculation automatically. When comparing a report with Overview Analytics, use the dates shown in the email and the same channel. You do not need to recreate your automations or broadcasts.
