Lay the foundation with list building
A strong sales strategy starts with a solid contact list. List building is the process of creating a list of best-fit leads. Use a contact database and filter by specific attributes and behavior data to target the right prospects. A well-built list saves you time, ensures targeted outreach, and supports long-term growth. Learn more about building highly targeted lists with Apollo's contact database of over 275M contacts.
Reach out to contacts via cold email
Once you have a contact list, use it by sending cold emails. Cold emailing is one of the most reliable channels for lead generation. Cold emailing is the process of emailing potential prospects who haven't previously engaged with your business. The best cold email campaigns are highly personalized and targeted, and can drive pipeline very cost-effectively. Not sure where to start? Check out these five sales sequences you can start using today!
Create multichannel campaigns with cold calls
Top sellers know: the magic is in the mix. Combine cold emails, cold calls, and LinkedIn touches, and you'll book up to 24% more booked meetings. While cold emails are great for initial outreach, cold calls provide real-time connection for tackling objections and making a lasting impression. Cold calling can be nerve-wracking, but it's also one of the most powerful ways to land leads and lock in meetings. Pro tip: Use Apollo's Dialer and get a local phone number for a better connect rate. Start with these cold calling scripts that actually book meetings.
