North American Pet Owners - Email List Building

We are compiling a database of emails for Pet owners in North America (Canada and USA.) They should belong to people who are able to buy from the Internet and ideally have purchased pet products recently online. List must be opt-in only. We are only interested in Quality and NOT Quantity. We have been offered the multi-million lists for small dollar amounts and are not interested. Lists must be verifiable. Out goal is to gather opt-in emails for at least 100,000 to 150,000 pet owners (there are over 40 million Pet owners in the USA.) This is the first category of many we will build, so good performance can result in an ongoing relationship. Here is a list of requirements: 1- Emails MUST be from USA or Canada. 2- Emails should be active, and preferably from people who recently made pet related purchases online. 3- You provide a sample of at least 2500 emails for a test – for verification so we can get data on bounces and valid addresses and opens. Min 5% open is the goal. If your test list meets our requirements, then we may purchase an incremental sample, and proceed in stages to complete the list building. 4-You must specify the phrase "I agree with your requirements" in your bid or PM. 5- We do NOT pay upfront payments. 6- We do NOT need to know the source nor the technique for acquiring the emails – they simply must be fresh quality opt-in Pet Owners who are interested in Pet related products. 7- Quality NOT Quantity is the key. 8- You should bid based on per 100,000 emails, if it's higher or lower than the range please mention that in the PM. 9- Email must be active, fresh, opt-in, quality, and uncommonly used. 10- We expect a high rate of email views/opens (more than 5%). 11 – You must offer at least three (3) references of previous work that can be independently verified by us. 12- If you cannot meet all of our requirements, you must mention that in the PM/bid. Please know we may choose more than one provider. Data may be delivered as a .csv or Excel file.
