<p>If a message fails because the inbox or phone ‘isn’t accepting messages right now’ then it’s up to you to decide if you want to send the message again or not.</p>
<p>Notify attempts to send messages for up to 72 hours before it returns that status.</p>
<p>If your user has provided you with multiple contact channels, you should send messages to the channel they’ve chosen as their preference. However there are some scenarios where you might want to send messages to more than one channel:</p>
<ulclass="list list-bullet">
<li>If a message fails to be delivered, you could try a different channel</li>
<li>If a message is delivered but the recipient hasn’t taken the action they need, you could try a different channel</li>
<li>If you need to urgently contact someone, you could email them and send them a text message at the same time</li>
</ul>
<p>If you’re using the Notify API these scenarios could be automated.</p>
<p>Replies to emails that you’ve sent will go directly to the reply-to address that you have set up for your service.</p>
<p>If you’re set up to receive text messages then your users can reply to messages you’ve sent, or can start an interaction by sending you a text message.</p>
<p>Receiving inbound text messages can allow your service users to:</p>
<ulclass="list list-bullet">
<li>confirm, cancel or change an appointment</li>
<li>register for a simple service</li>
<li>provide follow-up information for an application</li>
<li>report something</li>
<li>provide feedback</li>
</ul>
<p>You’ve then got the option to automate the processing of the messages you receive, or to view them in Notify.</p>
<p>If you automate the processing of text messages you receive, then you should have a manual process in place to deal with messages that can’t be automatically processed.</p>
<p>If you’d like your service to receive text messages, then <ahref="{{ url_for('main.support') }}">let us know</a>.</p>
<h2id="messagedeliveryandfailure"class="heading-medium">Delivery and failure</h2>
<p>This means the text message has been sent to a valid international phone number, but delivery receipts aren’t provided by mobile networks in that country.</p>
