How do we migrate SMS subscribers from another provider? You can carry over your contacts by uploading them from a file. During the import process, you can map the SMS channel opt-in date and also choose the subscription status. Just keep in mind that you won't be able to migrate the TCPA consents you have collected from the different providers. Omnisend only shows its approvals, so if you want to keep messaging your clients, you can import consent records as a custom property in Omnisend.

Do we have a double opt-in for SMS, and is it required in EU law? It is not possible to send the double-opt-in notification via SMS, but it is also not required by the GDPR. According to the GDPR policy, adding the corresponding information to your signup forms and a check-box for the double-confirmation action is sufficient.

What happens if the phone number is incorrectly formatted and the SMS bounces? Omnisend doesn't send SMS messages to phone numbers recorded in invalid formats. However, it can happen that the country code is not correct; in that case, we attempt to send the message and charge you for that, but once it bounces, we unsubscribe it for you. So, you won't have to pay to send SMS to such undeliverable subscribers in the future. More about SMS bounces here.

Is it possible to see the content of the SMS Campaign that was sent already? It is impossible to view the message's content in the Reports section, but you can create a copy of the Campaign and check its content in the draft.


What type of SMS messaging is Omnisend using? Omnisend uses toll-free numbers to send your messages.

Is it possible to add a link to the Subscriber preference center to the SMS message? Any personalization tags available in the personalization menu can be added to your SMS message, which means you can add a link to the subscriber preference page to any message. The only exception is the transactional flows within your Automations that should be sent to all contacts despite their subscription status and preferences.

Does the unsubscribe link and Stop instruction in the SMS characters count? Both unsubscribe link and Stop to opt-out instruction are added up to the total number of characters in your SMS message. Since these instructions have different lengths, the character count for the message sent to the US recipients will be longer than for the rest of the world.

 

Why do you need to shorten links, and why can't I use my own domain? Shortening your links reduces character count, helping to address two problems — decreasing message size and enabling clicks and sales tracking. The decision to use the Omnisend domain is influenced by two factors — the complexity of the setup process and the advantage of avoiding additional third-party flows. Additionally, using the Omnisend domain offers full deliverability support. You can rest assured that any domain-related issues will be identified and resolved promptly. While using your own domain might risk being blocked.

Is it possible to check how many folks replied STOP or opted out of SMS? Or replied HELP? Adding an opt-out instruction to the SMS message is mandatory for the US recipients, while it is somewhat optional for the rest of the world. In the Campaign reports, you will see the number of contacts that have unsubscribed out of those that had this option.

Unsubscribe rates from the Automated messages will be shown in the Last Campaign report.

Is it possible to send unique discount codes via SMS message? Yes, you can send unique codes in Automations. However, there is no built-in solution for generating unique codes in campaigns. You can add a custom property with unique discount codes assigned to each subscriber. Keep in mind that this property should be added to your contacts' profiles, and therefore, it can only be used in SMS Campaigns.

Does Omnisend automatically add country codes to the phones imported from the checkout? Yes, Omnisend adds the country codes to the contacts' phone numbers based on the location your customers select at checkout.

Is it possible to reply to SMS messages? Integration with Gorgias lets you set up two-way SMS messaging, where your support team will receive the replies and can message your contacts back. This functionality is based on the STOP and HELP replies processing and can be implemented for US recipients only.

Can I send MMS messages? Yes, you can send MMS messages to the United States and Canada. For more information, click here.
