The original reason this site was born :-) Being part of the committee of a race series we were paying $50+ a month for our email marketing service. We use Amazon SES and host a email marketing web application. Contact us for pricing which will depend on your needs but we will save you money.
Do you run a series of races? Sometimes its a nightmare keeping track of everything. We offer indiviual race and series scoring. We also can handle individual race and series registration. Contact us to discuss your needs and pricing.
