Mass email not working anymore

[luckejuin]

Hi,

Mass emails are not sent out; stay on pending. Nothing in logs.
Test email work fine.
Schedule job is active/running but the last log entries are from our previous mass email in July. Nothing more recent.

Any hint on what else to check?

Thanks,

Check whether a collation for 'lower' column in 'email_address' table is utf8mb4_unicode_ci.
