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

MailGun 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 its intended recipient or may land in a SPAM folder.

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

Ensure up-to-date SPAM protocols and filters

If your IT organization or the IT organization managing guests' email servers is using outdated SPAM filtering technologies and/or protocols, they may be inadvertently filtering or withholding delivery of email invitations from RSVPify and other external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

Use email best practices

  • Use proper text and image ratio. Avoid image-based content.

    Spam filters tend to block image-heavy content. Plus, even if they don’t, some recipients use email providers that disable images by default.

    Mailchimp advises a ratio of 80% text to 20% images in an email.

  • Optimize images included in your email

    To avoid image size impacting your deliverability, we'd recommend uploading images no larger than 100kb.

    Optimize and compress your image(s) with TinyPNG or any other image optimizer tool to reduce the file size.

  • 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    Some older, outdated email filters will automatically flag a message as spam if it simply includes certain keywords.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...

  • 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.

Check to see if any emails bounced (email campaigns)

A red envelope icon indicates that the email was undeliverable. See how to view email reports/status here.
