RSVPify is integrated with a 3rd-party enterprise email tool called SendGrid. All emails sent by RSVPify, including email invitations and guest mail blasts, are routed through SendGrid.

SendGrid is built to ensure maximum deliverability of email messages, and to keep emails out of SPAM folders. Despite these efforts, however, sometimes an email may not reach it's intended recipient or may land in a SPAM folder.

In such cases, there are a few troubleshooting protocols that we recommend:

Check to see if any emails bounced

A red envelope icon indicates that the email was undeliverable. Please follow the steps in this article to address any bounced emails. 

Confirm the correct email address is associated with the party in question

Ensure that one single, correct email address is associated with each party on your Guest List. At this time, each party may only be assigned one primary email address. If your invitation is addressed to multiple individuals, you can include the names of each individual in a party (Here's How).

Make sure the 'From Email' field is set to ''

While it is possible to make it seem as though an invitation came from your email address, because we can't digitally sign these emails as coming from you, we do not recommend this approach. We recommend keeping the From Email as its default value, and customizing the From Name and Reply-to Email only for maximum deliverability.

Ensure up-to-date SPAM protocols and filters

If your IT organization, or the IT organization managing guest's email servers is using outdated SPAM filtering technologies and/or protocols, they may be inadvertently filtering or withholding delivery of email invitations from RSVPify and other external email senders.

  • Reach out to your IT team to inform them of the issue and inquire about next steps. Ask if they can 'release' emails sent by RSVPify
  • Add '' and (as a domain) to your organization's 'safe senders' list
  • 'Whitelist' RSVPify's dedicated email server IP addresses:

Add a physical mailing address to your email's footer

Some email filtering technologies are less likely to flag an email as SPAM if a physical mailing address for your organization or person is included at the bottom of your invitation or email message. This suggests to automated filtering services that the email is originating from a trusted source that has a physical address that they can be reached at (and not some "fly by night" spammer).

We recommend including a physical mailing address in small gray text in the bottom of your email invitation or message.

Avoid use of 'spammy' keywords in your invitation or email

Some older, outdated email filters will automatically flag a message as spam if it simply includes certain keywords. Some keywords to watch out for: Free, act now, cheap, all natural, amazing, buy now, click here, discount, earn, cash...
