Do you use some kind of e-mail marketing platform?
If you do not use it, I would highly recommend using one. It gives you more free time, because it's mainly automated and gives you more opportunities for designing an e-mail which looks more attractive.
I'm a marketing director at retail hardware distribution company. I have also 4 years of knowledge and know-how in internet marketing (especially Facebook, E-mail and LinkedIn). I could help with writing and automation of e-mail marketing. Even choosing a best platform for your needs.
PS! I'm not a regular freelancer, mainly I buy services from here. Also, I'm not a cheap person to work with, because I have a masters degree in marketing and I'm not stupid. I personalize a lot and won't be happy with bad and non-strategic marketing.
I'm looking forward how I can help you, even beyond this task.
