So far, the best service I have found that is both reliable and free is RSS by email (https://rssby.email/). I have been using it the last couple of weeks and found it just as reliable as Feedburner. See below for instructions on how to set it up.
To subscribe to content on this website by email, send an email to add@rssby.email with the following as the subject and the body of the message:
https://www.dividend-growth-stocks.com/feeds/posts/default
After sending the email:
- If your subscription is successful you will get a confirmation email.
- You can put a UTC hour in the subject, the email will be sent at that time.
- Emails are sent daily by default, this can be changed to weekly in a link from your feed email.
- Feeds that have not been updated after 90 days will be automatically unsubscribed to reduce server load.
- The feed can be unsubscribed from by sending the same RSS link used to subscribe to unsubscribe@rssby.email
My apologies for any inconvenience this may cause you.
