We have worked with some clients who were looking for some opportunities in Europe, South America, and Southeast Asia, and had to develop a position and reputation for their products and services.
The email marketing campaigns were very specific and focused. We combined email and social media marketing, worked on providing contents in the SM, and then used other marketing tools to be in front of their market pretty much 24/7. It took about 6 months and a lot of posting of industry content. In the end they achieved their goal.
Email marketing can be challenging. It is all about content and timing. I recently search the words "Social Media Marketing" and there were almost 900,000,000 results in Google. It is all about ranking and content. You need to be able to connect.
Start with social media and then move to email marketing. The contact data has to be very good to avoid a visit to the spam folders of the recipients.
I hope this helps. Good luck.
