SendGrid sends b
illions of email every month for thousands of customers, so it’s no surprise that our amazing support staff handles a ton of questions. Whether it’s helping new customers integrate
or informing customers of changes to DMARC policies
, they handle it all.
We picked a few common questions SendGrid Support received over the last month to highlight here along with their answers:
Why isn’t my email-to-sms working?
If you’re considering sending large numbers of SMS messages to customers from your SendGrid account, you may run into some problems. The bandwidth for SMTP-to-SMS is very narrow because network providers need to be able to predict traffic and prevent spam messages. Our post Email to SMS
goes into even more detail.
What are SPF records?
SPF stands for Sender Policy Framework
. This is a security measure SendGrid allows customers to use to further prevent sender address forgery. We’ve detailed the process for implementing and configuring your SPF record and how to incorporate it into authenticating your account in SPF Records Explained
What is domain authentication?
We strongly suggest that all customers set up domain authentication for their accounts. Domain authentication is the process of masking Twilio SendGrid from the sending process, email headers, and links within the messages you send. Not only does domain authentication improve deliverability and customer engagement, it also improves your sending reputation. You can follow the Domain Authentication Wizard
or watch the domain authentication video tutorial
How does SendGrid bill me each month?
At the beginning of each month, SendGrid bills its paying customers. This bill is for the upcoming month of usage, as well as any overages, usage charges, or newsletter usage incurred during the previous month. You can learn more about this process and find more useful information in our post titled: Billing Information and Resources
How should I handle “unsubscribes” to my email campaign?
Managing your subscriber list is an essential part of any email campaign. If a recipient wants to unsubscribe, make sure they’re taken off your sending list as soon as possible. Otherwise, your emails could be marked as spam, dropping your sender reputation. You can learn how to implement unsubscribes
in two different way in Unsubscribes Explained
How can I test my email sending speed?
If you're sending large volumes of email and are interested to see how long it takes for an email to be delivered, we've developed a special domain for users to safely test their SMTP relay
speeds. Plus, there's no risk to your your sending reputation by testing multiple times. Visit our Safely Test Sending Speeds Knowledge Base
post to see how to do it.
