SendGrid helps you focus on your business without the cost and complexity of owing and maintaining an email infrastructure. Our technology, advanced analytics, and flexible APIs are designed for all types of email - from transactional messages generated by an application to double opt-in marketing campaigns.
Does it harm my reputation if I change the "From" name when using the same email address (even if it is beneficial to my customers)? PKS: Email addresses can be divided into two parts, the "Friendly From" and the routable part. For example, "Franklin Fasteners" . We don't think you'll incur a reputation hit if you change the "Friendly From" part (e.g. "Franklin Fasteners") but you are more likely to incur a reputation hit if you change the routable part. Not all system use the "from" address for reputation, but some do. They are more likely to associate your sending reputation to your IP or your DKIM signature (inserted into your message headers) or a combination of both.
Can I send through the same email from a different domain name on a daily basis? PKS: You can send the same message content from a different domain on a daily basis, but many spam filters will recognize similar content from different domains, so if one domain gets a bad reputation, messages with the same format or content will probably be blocked too.
We have been on board with SG for a few weeks and we are constantly improving our practices, but for some reason our reputation has not improved. PKS: Your sender reputation is affected by the number of spam complaints. If you got off to a bad start and sent to a lot of recipients who didn't want your message, some of them may have marked the message as spam. Sometimes people will mark messages as spam days or weeks (even months!) after receiving the message. If a steady (but hopefully declining) stream of spam complaints trickles in, then that will degrade your sending reputation. The reputation is bound to improve after the complaints abate. Also ensure your bounce rates are low. Have you checked to see if your sending IP or domain is on a blacklist? (Try http://multirbl.valli.org/lookup/ with both.) If you are blacklisted, sometimes you'll be able to discover the reason and reach out to get yourself delisted once you've made the necessary changes to your sending practices.
My list is past customers and people that signed up for email specials and promotions. Some of the names are 10 years old. How does SendGrid help in cleaning that up? What do I do and what does SendGrid do? CB: SendGrid delivers the mail you send. You are responsible for your own list hygiene. That being said, a win-back campaign could be a great way to clean up your list and identify engaged users. Take your list and ask them to "subscribe" to your list and outline exactly what they would receive. This is a great way to take advantage of the names you already have but to ensure they are active and interested. – less–ZoomInfo
