Your emails land at 3 a.m. in your lead's time zone
Selling across time zones means your 10 a.m. is someone else's night. Super Intelligent Sender waits for theirs.

How do I send cold emails in each recipient's local time?
Give each lead a time zone and send only inside their working hours. Super Intelligent Sender keeps a UTC offset for every lead, taken from a timezone column in your import file, or from the country domain of their company or email, or from the brand's default. It sends only inside that lead's business hours and working days, within the campaign's own schedule, and Check timing warns you before launch if campaign and mailbox hours never overlap.
Signs you have this problem
- Most opens happen hours after the email was sent
- Leads abroad receive emails on their Saturday
- You run separate campaigns for every region just to change send times
- A campaign "runs" but never sends to one region
What Super Intelligent Sender does about it
A time zone per lead
From your CSV, the country domain, or the brand default.
Business hours and days
Emails wait for the lead's working hours and skip their weekend.
Check timing
See before launch whether campaign and mailbox hours overlap.
Brand time zones
Each brand has its own default time zone for leads without one.
What Super Intelligent Sender does not do
Each lead keeps a fixed UTC offset, so daylight saving changes are not applied automatically. For countries with several time zones, such as the US, Canada and Australia, add a timezone column to your import file.
