As a small business owner, you will want to focus on building your email list. Whether you have a digital business or an on the ground location, you will want to collect your customers emails – and the emails of everyone in your network, if you are B2B. Often this can be done by offering a promise of keeping your clients/customers up to date with special offers, discounts, and events, or by giving them specialized information that will solve their problem.
The type of email campaign you launch will depend on your goals and where in the customer journey you find your prospect.
For example Drip marketing can help you boost sales by turning visitors into buyers, increasing repeat purchases, and re-engaging a dormant audience. By communicating your company’s value, you build a relationship with your audience and demonstrate that you’re a great resource for their needs.
I use MailChimp. Here they explain the process but any reputable email service will have this feature.
