What Actually Works:

Professionals respond well when you sound humble and respectful. Start with “Buenos días” or you can also say “Buenas tardes” to show courtesy. Use clear language and slow your pace a bit. Give them some space to ask you questions. When a trust is built, agreements happen quickly.

What Doesn’t Work:

You don’t have to start with formal introductions or directly with the sales pitches. Jumping straight into offers might turn people off. So, don’t rush the conversation or push for quick decisions. You need to give them time to respond. Also, avoid calling late at night (after 5 PM local). Most professionals at this time are wrapping up their work.

When to Actually Call:

Call midweek. Tuesday to Thursday would be the best. The sweet spot is 10 to 11 AM ET, which matches late morning in Argentina. If you are on the West Coast, try 11 AM -1 PM PT. Avoid early mornings and late afternoons. A well-timed call can easily double your chances of getting through.
