Email verification and attendee notifications

eWebinar checks registrant email addresses to protect deliverability and keep inbox placement healthy for everyone who uses eWebinar email (including when notifications go out through SendGrid or SMTP).

Attendee notification emails are not sent to addresses eWebinar has marked invalid. For other cases, eWebinar verifies deliverability before sending attendee mail, then remembers the result so it does not re-check every time.

Choose when to verify (per eWebinar)

On the Notifications tab (and also under registration settings), open Email verification. Each eWebinar has two modes:

• During registration (default). eWebinar checks the address while the person registers. If verification fails, they are asked to use a different email address. This adds a few seconds to registration submissions. The address that failed never reaches your CRM or other integrations.
• Only before sending. Anyone can register. If verification fails, notification emails aren’t sent. All addresses still reach your integrations without verification at signup; any that fail are flagged in your registrant list. Use this when you want faster registration and are comfortable cleaning bad addresses from your CRM afterward.

How verification works by registration path

• Registration forms and widgets (During registration). eWebinar checks the email during signup. If verification fails, the person is asked to use a different email address before the registration completes.
• Only before sending, API, Zapier, and other auto-registration paths. The person can become a registrant first. Before the first attendee notification is sent, eWebinar attempts to verify the address. The result is saved: valid and unclear addresses can receive mail; invalid addresses are suppressed. Later notifications reuse that saved result instead of verifying again every time.
• Late capture (ungated or chat email capture). When someone only gives an email after joining, eWebinar still applies the same send rules. Until a successful check has cleared them to receive mail, automations and integrations should treat the address as not yet verified for deliverability.

CRM and Zapier when an address fails

Integrations (including Zapier and CRM actions) can listen for Email address not deliverable. That trigger fires the first time eWebinar finds that a registrant’s address does not exist or cannot receive mail. Because the check often happens just before send, it can fire days after they registered. Use it to mark or remove the contact in your CRM. It fires once per registrant, not for every email that is then skipped.

This is especially useful with Only before sending, where the contact may already be in your CRM before the mailbox check runs.

When a check cannot finish

Sometimes the deliverability check cannot complete (for example, a temporary outage on the verification side). In that case eWebinar still sends the notification. Only a definitive “invalid” result blocks mail. That way a registrant does not lose their confirmation or join link because a check timed out.

When the check could not finish, eWebinar may try again on a later notification so a clearer result can be saved once the check is working again.

Why we do this

Sending to bad addresses damages sender reputation and can cause email providers to block notifications for many customers—not just one account. Checking deliverability keeps inbox placement healthier for everyone. Failing open when the check itself is unavailable keeps real registrants from missing join links.

What to check if emails are missing

1. Confirm the registrant’s email is a real, deliverable mailbox (no typos, no disposable throwaways you intend to reach).
2. Check this eWebinar’s Email verification mode on the Notifications tab.
3. For API or Zapier registrations, wait for the first notification attempt to finish its check, then see whether later reminders or follow-ups go out once the address is cleared.
4. If you use CRM or Zapier automation, look for an Email address not deliverable event for that contact.
5. If you send through SendGrid or SMTP, also confirm domain and sender authentication in that provider—verification and deliverability both matter.

Follow-up email audiences

Follow-up emails live on the Notifications tab of the eWebinar editor, in the Follow-ups after eWebinar section. Each one goes to a single audience that you pick from the Add a follow-up menu (and can change later in the email's To: dropdown), so a no-show never gets a "thanks for attending" message. The menu lists To all registrants first, then the audiences of people who watched under Watched and of people who didn't under Didn't watch:

Audience	Who receives it
To all registrants	Everyone who registered, whether or not they watched. It is timed from the end of their scheduled or just-in-time session, or from their on-demand registration.
To registrants who watched some	Everyone who watched any part of the eWebinar, whatever session they registered for, watching the replay included. It goes after their own session ends.
To registrants who watched but didn't complete	People who watched some of it but have not met your completion requirements. Someone who never joined is not in this audience.
To registrants who completed	People who completed the eWebinar. When completing it takes only watching, the menu names the percentage, for example "To registrants who completed (watched 95% or more)".
To registrants who missed their scheduled session	Registrants of a scheduled or just-in-time session who didn't watch it, sent after the session they missed ends. Offered unless the eWebinar is on-demand only.
To on-demand registrants who haven't watched yet	On-demand registrants who haven't started watching, timed from their registration (for example, one day after registering) and checked again when it is due. Offered when the eWebinar has on-demand sessions.

There are no replay audiences, since people register for an on-demand session instead of a replay. A follow-up written for replay registrants is in the same list with the condition Registered session type is Replay, so it still reaches only the people who registered for a replay when that was offered.

You can add as many follow-up emails as you like, each with its own audience and send time (for example, one hour after the session ends). To narrow an audience further, for example to people who have not converted or who watched more than half, add conditions (see below).

Set up a follow-up for one audience

1. Open the eWebinar editor and go to the Notifications tab.
2. In the Follow-ups after eWebinar section, click Add a follow-up and pick the audience, or duplicate an existing follow-up.
3. Check the audience in the To: dropdown, and under Conditions: add any rules the registrant must also meet.
4. Write the email for that audience, set when it sends, and save.

Repeat for each audience you want to reach. A registrant only receives the emails whose audience they match and whose conditions they meet.

Skip follow-up emails for attendees who converted

Every follow-up email can have Conditions: rules on the registrant's properties that must all hold when the email is due, or it is not sent to them. They are set up like an interaction's conditional display logic. To skip attendees who converted, add the condition Converted is false. It replaces the Don't send if attendee has converted toggle: a follow-up that had the toggle on has this condition instead. Add it to offer reminders you do not want to send to people who already acted; leave it off for thank-you or onboarding emails that should go to everyone.

"Converted" means the attendee triggered the eWebinar's conversion event: a Contact form submission or Next eWebinar registration counts immediately, while Call to action and Special offer conversions count once your conversion tracking code fires on the destination page (not on the click itself). Attendance and watch time do not count as a conversion. See How do I track conversions that result from people attending my eWebinar? for details.

Conditions are per notification, not per eWebinar, so you can skip the "last chance" reminder for customers while still sending them your onboarding email. Besides Converted, a condition can test what the registrant did, such as Completed, Purchase amount, Highest watched % or Session type (with operators such as is true, is false, is more than and is less than), as well as their registration answers and their responses to interactions. Each follow-up in the list names its conditions under its heading, for example "Only if Converted is false".

Follow-up email	Converted is false
"Last chance: the offer expires tonight" reminder	Added
Welcome or onboarding email for new customers	Not added
"Missed it? Here's the replay" email to no-shows	Not needed (the audience already limits it to people who did not attend)

Registration notifications for your team

eWebinar can email your team every time someone registers, or roll the day's registrations into one message. The setting is per eWebinar, on the Registration tab under Registration notifications.

1. Open the eWebinar editor and go to the Registration tab.
2. Scroll to Registration notifications and turn on Enable registration notifications.
3. Choose For every registration or A daily summary (see below).
4. Under Send notifications to these email addresses, enter up to three addresses that should receive the alerts, separated by commas.

For every registration or a daily summary

Option	When the email is sent	Best for
For every registration	Immediately, each time someone registers.	Low-volume sales eWebinars where each lead goes straight to a rep.
A daily summary	Once a day, listing everyone who registered in the last 24 hours.	Evergreen eWebinars with many registrations a day, where one email per registrant is too noisy.

These alerts go to your team. They are separate from the emails your registrants receive (set up on the Notifications tab) and from moderator chat notifications (set up on the Chat tab).
