Email, SMS or WhatsApp: when to use each channel
When you build a campaign in Nevent, the wizard’s second step asks you to choose a channel: Email, Push, SMS or WhatsApp. That choice affects how far your message reaches, how quickly the recipient sees it, and what you need to have set up before sending. This guide explains what each channel offers and when one makes more sense than another.
Nevent’s four channels
Section titled “Nevent’s four channels”Per the platform’s documentation, Nevent has four communication channels: Email, Push, SMS and WhatsApp. Of the four, Email and Push are active by default on every account; SMS and WhatsApp require activation from Settings > Channels before you can use them.
This guide focuses on the three channels most used for promotional campaigns and direct communication with attendees: Email, SMS and WhatsApp. Push has a different use case (in-app mobile notifications) and is outside the scope of this comparison.
Email: the reference channel for event campaigns
Section titled “Email: the reference channel for event campaigns”Email is Nevent’s main channel and the only one that works with zero extra setup. From day one you can build a template with the visual block editor, pick an audience segment and launch a campaign.
What email offers
Section titled “What email offers”Rich content. The template editor lets you combine images, text, call-to-action buttons, columns, dividers and social icons. It’s the channel that gives you the most room to tell an event’s story: poster, lineup, date, venue and purchase link, all in a single message.
Full measurability. Every email campaign generates a report with five sections: Summary, Deliverability, Unsubscribes, Segments and Engagement. You can see how many emails were delivered, how many were opened, how many links were clicked and who unsubscribed. The platform’s reference ranges put a healthy open rate above 25% and a healthy click rate above 5%.
Control over deliverability. Nevent lets you set up a dedicated domain so your emails go out from your own domain instead of the platform’s shared one. This improves inbox placement and protects your sender reputation. The SPF, DKIM and DMARC records configured in that process are the technical standard mail servers use to decide whether a message is legitimate.
Two campaign types. Nevent automatically detects whether a campaign is marketing (promotions, newsletters, early birds) or transactional (confirmations, reminders, access). Marketing campaigns include an unsubscribe link and respect user preferences; transactional ones don’t.
When to use email
Section titled “When to use email”Email works well when the message has visual content that justifies the format, when you need to measure performance in detail, or when the attendee’s buying cycle is longer and deserves an elaborate message. It’s the ideal channel for ticket launches, program announcements and pre-event reminders.
What to keep in mind
Section titled “What to keep in mind”Email lives alongside mail providers’ spam filters. Keeping bounces low, respecting unsubscribes and sending to lists with consent are practices that protect your sender reputation. If your hard bounce rate exceeds 2% or your spam complaint rate exceeds 0.1%, those are warning signs by Nevent’s reference ranges.
SMS: direct immediacy to the phone
Section titled “SMS: direct immediacy to the phone”SMS reaches the contact’s mobile phone as a text message, with no need for any app to be installed or an active email account. It’s the channel with the highest open rate, according to Nevent’s documentation on channel activation.
What SMS offers
Section titled “What SMS offers”Immediate delivery. SMS doesn’t compete with a full inbox or a spam filter. The moment the message goes out, the recipient gets a notification directly on their lock screen.
Concise format. SMS is plain text: no images, no design buttons, no columns. That makes it ideal for short, direct messages: an access reminder, a last-minute notice, a discount code with a deadline.
Recognizable Sender ID. When setting up the SMS channel in Nevent, you can define a Sender ID of up to 11 characters — the name that shows as the sender on the recipient’s phone (for example, DEMOFEST or MYFESTIVAL). The recipient sees your event’s name, not an unknown number.
When to use SMS
Section titled “When to use SMS”SMS fits urgent or high-importance messages that need to arrive and be read right away: the reminder the day before the event, a last-minute schedule change, a doors-opening notice or a security communication. It also works well for promotions with a very short deadline, where immediacy is key.
What to keep in mind
Section titled “What to keep in mind”SMS isn’t active by default. To send it you need to activate the channel from Settings > Channels, add at least one Sender ID and, for Spain, handle the alias registration with the CNMC before September 15, 2026. Per Nevent’s documentation, carriers will block SMS whose sender isn’t registered starting that date. Nevent handles that registration for you if you contact support.
SMS doesn’t have an individual open report comparable to email’s. It’s a sending channel, not one built for detailed engagement measurement.
WhatsApp: the messaging app channel
Section titled “WhatsApp: the messaging app channel”WhatsApp lets you send campaigns directly to the messaging app installed on the contact’s phone. Unlike SMS, the message arrives inside the WhatsApp conversation, where the recipient can see the read status.
What WhatsApp offers
Section titled “What WhatsApp offers”Read confirmation. WhatsApp offers read receipts, giving an extra layer of information about whether the message was seen. Nevent’s channel activation screen explicitly mentions real-time metrics and read confirmation as benefits of the channel.
Richer content than SMS. A WhatsApp template can include an image, video or PDF header, a message body with text and personalization variables, a footer, and up to 10 buttons of two types: quick replies and calls to action (external URL or phone number). That makes it more expressive than SMS, though less flexible than email in terms of design.
Personalization variables. As with email, you can insert the contact’s name or other data into the message body using the variable format (double curly braces with a number). Nevent replaces the variable with each contact’s real data at send time.
Categories aligned with use: Marketing (promotions, early birds, lineup announcements) and Utility (purchase confirmations, access notices, account updates). The category is set when creating the template and can’t be changed afterward.
When to use WhatsApp
Section titled “When to use WhatsApp”WhatsApp is useful when the contact regularly uses the app and the level of closeness with the brand justifies it. It works well for access reminders with a direct link, ticket-launch announcements to an audience that already consented to this channel, or purchase confirmations in Utility format.
What to keep in mind
Section titled “What to keep in mind”WhatsApp requires two activation steps before you can send. First, connect a WhatsApp Business account through Meta’s verification flow from Settings > Channels. Then, every template you want to use must be submitted for review and approved by Meta, which can take anywhere from a few minutes to 24 hours. Only templates with Active status can be selected when creating a campaign.
If Meta rejects a template, you need to create a corrected new version; a rejected template can’t be edited directly.
How they relate to credit cost
Section titled “How they relate to credit cost”All three channels consume credits from your Nevent plan. The review step of the campaign wizard, the last one before launch, shows the estimated cost in credits along with your available balance. You can check that before confirming any send.
The monthly credits included in your plan reset each billing cycle and don’t roll over. If a high-volume send uses up the month’s balance, you can buy additional credit packs from the Billing Center to reactivate capacity without waiting for renewal.
Comparison table for the three channels
Section titled “Comparison table for the three channels”| SMS | |||
|---|---|---|---|
| Activation required | No (active by default) | Yes (Sender ID + CNMC registration) | Yes (WhatsApp Business + Meta template approval) |
| Content format | Rich (images, buttons, columns, visual design) | Plain text | Text with optional media header and buttons |
| Immediacy | Medium (arrives in the inbox) | High (direct notification on lock screen) | High (notification in the messaging app) |
| Read confirmation | No (estimated open rate) | No | Yes |
| Campaign reports | Complete (delivery, opens, clicks, bounces, unsubscribes) | Limited | Real-time metrics per the documentation |
| Campaign types | Marketing and Transactional | No documented type distinction | Marketing and Utility |
| Mandatory prior review | No | No | Yes (Meta reviews and approves every template) |
How to decide
Section titled “How to decide”There’s no universally better channel: each one serves different moments within an event’s lifecycle.
Email is the natural starting point for any organizer beginning with Nevent. It requires no setup, allows rich designs and offers the most complete report. It’s the reference channel for launches, newsletters and elaborate communications.
SMS wins when urgency and immediacy are what matter. If you need the message to arrive and be read in the next few minutes, SMS is the right tool. Its format limitation is also its advantage: it forces you to get to the point.
WhatsApp combines SMS’s immediacy with a bit more content richness and read confirmation. Its weak point is the initial friction: connecting the business account and waiting for Meta’s approval on every template. Once you get past that process, it’s an effective channel for audiences used to communicating through that app.
In practice, the three channels complement each other. A typical event sequence might combine a full-design launch email, a reminder SMS the day before, and an access confirmation over WhatsApp.
