Event SMS confirming registration for a two-wheeler dealership launch day with pass code and map link, and a morning reminder

Can you send event invitations by SMS in India?

Yes. An invitation to people who have not registered is promotional SMS, sent from a numeric header between 10 am and 9 pm to non-DND numbers, or as service explicit to customers who consented. Once someone registers, their confirmation, joining link, venue reminder and entry pass are service implicit and can be sent at any hour.

What are the best practices for event invitations?

Do this

Separate invitations (promotional) from confirmations and reminders (service implicit); never mix them in one template
Schedule invitations between 11 am and 7 pm on weekdays, well inside the promotional window
Send the webinar link 15 to 30 minutes before start, not the night before
Give a pass code or registration number for quicker entry at the venue

What to measure

Registrations per 1,000 invitations sent
Attendance as a share of registrations
Invitation link click rate by list segment

Questions about SMS event invitations

Is an event invitation SMS promotional?

Yes, when it invites people who have not registered. It must be sent from a numeric header, only between 10 am and 9 pm, and will not reach DND numbers. To invite existing customers on DND, collect their consent and send as service explicit SMS.

Can I send a webinar link by SMS?

Yes. Registration confirmations and joining links to registered attendees are service implicit. The link domain must be whitelisted on your DLT entity, which matters for video platform links; many organisers use their own short-link domain that redirects to the meeting.

How many reminders should I send for an event?

For most events, three messages work: confirmation at registration, a reminder the day before and one a few hours before. For webinars, send the joining link 15 to 30 minutes before start. More than that tends to annoy registrants.

Can I invite people to an exhibition or trade fair by SMS?

Yes, as promotional SMS to non-DND numbers you have a lawful basis to contact, such as past visitors and customers. For trade visitors, dealers and distributors already doing business with you, service explicit with consent reaches them even on DND.

Should event invitations go by SMS or WhatsApp?

WhatsApp is better for a visual invitation with a poster and RSVP buttons, for contacts who opted in. SMS reaches a wider list and is reliable for confirmations and same-day reminders. Many organisers invite on both and confirm by SMS.

Can I send event passes or QR codes by SMS?

You can send a pass code or a link to the QR code on a whitelisted domain. SMS cannot carry images. For an image pass, use WhatsApp or email, and keep the SMS as a backup with the code in text.
