Smartlead Auto-Adjust Warmup warning — what is it?
Updated Nov 6, 2026
If you use Smartlead for warm-up, disable the "Enable Auto-Adjust Warmup/Sending Ratio" option.
Leaving it enabled overrides your warm-up settings and sends 16–120 warm-up emails daily — even if you configured 8–10 per day.
This has been causing Microsoft tenants to get blocked. All ScaledMail Outlook users should disable this setting.
