For Users Sending Email from a Company Domain Name
1. Email sent to yourself or to others in your company
When you send an email with CorpNote, your real email address is used as the 'from' and 'reply to' email address, even though they are sent from CorpNote's email server. While this is a legitimate practice for third-party email services like CorpNote, it's also a trick that's used by spammers called "spoofing". Your email administrator may have an email filter in place that blocks incoming emails that say they're from a company email address, but are sent from another email server.
The solution requires you to contact your email administrator and ask them to white list (allow) emails from the CorpNote email server. (view instructions)
2. Improving deliverability of email sent to others
One of the reasons email gets blocked by internet and email providers is that it fails a basic test — the Sender Policy Framework (SPF) lookup — which sends a request to the domain in the 'from' address of the email to look up the sending server and see if the sender is legitimate.
Since CorpNote uses your real email address as the 'from' and 'reply to' address, but the messages are sent from our email server, the SPF lookup will fail unless your SPF record lists CorpNote as an approved, trusted sender. The SPF record can be accessed and changed by your email administrator. Once they add our server name and IP address as an approved email sender, your chances of getting through SPAM filters are greatly increased.
The solution requires you to contact your email administrator and ask them to add us to the DNS record as an approved email sender. (view instructions)
What to tell your email administrator:
Email messages sent through CorpNote are being rejected due to failing the Sender Policy Framework (SPF) lookup. The sending domain's SPF record does not include the sending IP address being used to relay the email. Please add the following server information to our domain's DNS to approve CorpNote as an email sender for our domain:
DNS Record Type: TXT
Value: v=spf1 include:spf.corpnote.com ~all
TTL: 3600 seconds or 1 hour
Your domain may have other entries in its SPF record, in which you will only need to add include:spf.corpnote.com directly after v=spf1
If you previously added an SPF entry for CorpNote's mail server, you can safely remove ip4:126.96.36.199 from your record during this time, as the include statement will also contain this address.
