Calendly emails going to spam? What you can do

If invitees say they never got your Calendly confirmation, or you're missing booking notifications, it helps to know who actually sends those emails. It isn't you.

Who sends Calendly emails

Calendly sends confirmations, reminders and notifications from its own address, notifications@calendly.com, not from your domain. According to answers in Calendly's community, you can't change the From address to your own domain; replies go to your Calendly account email.

That means fixing your own SPF, DKIM or DMARC won't change how Calendly's emails are filtered. What gets them filtered is the recipient's spam filter, sometimes a strict company filter, judging Calendly's sender.

If your invitees aren't getting them

Ask regular contacts to add the sender. Adding notifications@calendly.com to their contacts or safe senders list, or marking one message as Not spam, helps future emails arrive.
Company inboxes: if invitees at one company never get your emails, their IT team may be filtering them. Ask them to allow Calendly's sender.
Calendar invites still work. Calendly adds the event to the invitee's calendar when connected, so a missed email isn't always a missed meeting. Tell invitees to check their calendar.
Send your own follow-up. For important meetings, a short personal email from your own address, confirming the time, is the most reliable message you can send. Make sure your domain is set up properly so that one gets through: run the free check.

If you're not getting booking notifications

Check your spam folder and mark the notification as Not spam. In Gmail, create a filter for from:calendly.com with Never send it to Spam. In Outlook, add calendly.com under Settings → Mail → Junk email → Safe senders and domains. On a company Microsoft 365 account, ask your admin to check quarantine. Also check the notification settings in your Calendly account, in case they're turned off.

Don't add Calendly to your SPF record

Calendly's emails don't come from your domain, so adding Calendly to your SPF record does nothing for them. Unneeded entries push your SPF record toward its 10-lookup limit and can break it for your real email.

Questions

Why are Calendly emails going to spam?

Calendly sends from its own address, notifications@calendly.com, and the recipient's spam filter decides. Strict company filters and inboxes that have never seen Calendly mail before are the most likely to filter them.

Can Calendly send emails from my own domain?

According to Calendly's community answers, no. Confirmations and reminders come from notifications@calendly.com, and replies go to your Calendly account email.

How do I stop Calendly emails going to spam?

Ask invitees to add notifications@calendly.com to their contacts or safe senders, or mark a Calendly email as not spam. Business invitees may need their IT team to allow the sender. For your own notifications, create a never-spam filter in Gmail or add calendly.com to Outlook's safe senders.

Should I add Calendly to my SPF record?

No. Calendly's emails aren't sent from your domain, so it has no effect on them, and extra SPF entries can push your record past its 10-lookup limit.
