Avoid being blocked by web mail companies for mass/bulk emailing?
Our company is sending out a lot of emails per day and planning to send even more in future. (thousands) Also there are mass mailouts as well in the ten thousands every now and then.
Anybody has experience with hotmail, yahoo (web.de, gmx.net) and similar webmail companies blocking your emails because "too many from the same source in a period of time" have been sent to them?
What can be done about it? Spreading email mailouts over a whole day/night? At what rate?
(we are talking about legal emailing just to make sure...)
Answer
You want to look at the following:
- add a bulk-header to your outgoing email (
Precedence: bulk) - look into SPF
- look into SenderID
- look into DomainKeys or DKIM
- look into CAN-SPAM act
- setup and handle email to abuse@
- build relationships with the important providers
- monitor the usual spam lists, work with them when you are on them
Also, most providers have pages setup where they explain how they want "bulk" email to look like when you are sending it to their customers. That general includes requirements for double opt-in, etc..
