Digital Marketing Services
Use a different type of the same method. If your daily newsletters are not being warmly received, try changing to a weekly or "event-only" format. You will be able to put more content in each newsletter, and your customers will respect that you understand their wants. You can even add these options, if your customers would seem to like it more.
Remember that patience is a virtue. No website started with a million hits a day, unless there was major marketing going on beforehand. Be patient and use tried and true tactics to increase your customer base gradually. It will be easier on both you and the reader, since you may be overwhelmed if a large number of people join at once.
Savvy digital marketing services double-check the email addresses they get from potential clients by using two lines of opt-in strategy. The first line is getting website visitors to surrender their email address. Then by soliciting a response - through an email newsletter offering a small but valuable freebie, perhaps - website owners can get their visitors to verify their own addresses.
