SMS Auto Reply: How Autoresponders Work (And Why Your Organization Needs One)

It’s a Sunday night at 9 PM when someone sends you a message. They may want to make a donation, have just signed up for an opportunity as a volunteer, or want to ask a question about your next event. Once you read their message, you do nothing; they receive no answer and are left confused, upset, and probably the last time they send you a message.

What is the cost of that silence? Donors move on; volunteers lose interest; supporters feel as if their opinions don’t matter. None of this has to happen.

With SMS autoresponder, when someone sends you a message, they receive within the second an automated response that is both professional and instant without having a human involved, therefore there is never a delay or dropped ball.

This guide will teach you how to use autoresponders effectively and everything you need to understand about how the SMS autoresponder works.

What Is SMS Auto Reply?

An SMS auto respond is an auto-response via text message that is sent within seconds when someone sends a text message to your phone. Once you set it up, it runs on its own, every time that someone sends you a text.

Think of it like an out-of-office reply through email but instead it is through text messages. In addition, it does not just say “I am away.” It will also confirm donations, welcome new volunteers, share details about your event(s), answer common questions, and/or redirect people to their next step.

By having an SMS Auto Respond program in place, the person sending the text message will receive a response in seconds compared to hours.

Quick Answer: What is SMS auto reply?

GOTV stands for SMS auto reply is an automated text message sent instantly when someone messages your number. It is triggered by a keyword or an inbound message and requires no manual effort once set up.

How Does an SMS Autoresponder Work?

The mechanics are simple. An SMS autoresponder works in two parts:

Keyword Trigger

A keyword is a word or a phrase that someone texts to your phone number in order to start the automatic Reply. For example when a person texts “GIVE” to your number they will receive a confirmation of their gift along with a link. If they were to text “VOLUNTEER” to your number they would receive a welcome message and next steps.

Keywords should be short, easy to remember and difficult to misspell. You can create as many keywords as you want, each keyword can be used to trigger a different automated Reply.

Automatic Response Message

The automatic response message that will be automatically sent to the person that texted you the keyword should be simple to understand and will include: Confirmation of their response, a link to a related resource, set of instructions or any other appropriate information to match their expectations for their keyword. Be concise, provide useful information and remain specific to their initial expectations.

Quick Answer: How does an SMS autoresponder work?

  1. Someone texts a keyword to your number
  2. The platform detects the keyword
  3. An automated response fires back instantly
  4. The person receives the message within seconds, no human involvement needed

Why Nonprofits and Campaigns Use SMS Auto Reply

SMS autoresponders aren’t limited to retail deals or restaurant promotions; they are also valuable for Nonprofits and political campaigns when it comes to their ability to respond quickly to supporters when the organization is small and/or operates at maximum capacity. Here are some of the ways that organizations find value in using SMS autoresponders:

  • Donation confirmations: Once a donor makes a contribution, they immediately receive a text acknowledging their support along with a link to view a receipt for their gift- no waiting, no doubts!
  • Volunteer sign-up confirmations: For all new volunteers once they text to sign-up, they automatically receive a welcome message with information about what has been done next.
  • Event registration confirmations: Simply send a text with the designated keyword from the event marketing material, and receive the details automatically!
  • After hours replies: When someone sends a text at 11:00 pm, they receive an automatic response letting them know the team will get back to them in the morning.
  • Keyword opt-in confirmations: For example -“Text GIVE to 55555 for the opportunity to join our donor community”- The autoresponder automatically handles the opt-in confirmation.

SMS Auto Reply vs Manual Responses

When dealing with a smaller group of supporters, it’s fairly easy to respond manually (e.g., typically one or two messages per day). However, as the number of supporters continues to increase, you will quickly realize that this method of processing becomes increasingly inefficient when your group is larger. The following provides a good example of this:

SMS Auto Reply Manual Response
Speed Instant — seconds Minutes to hours
Availability 24/7 — never misses a message Business hours only
Consistency Same message every time Varies by person and mood
Scalability Handles 1 or 10,000 texts equally Breaks down as volume grows
Cost Low — pay per message High — staff time

What Makes a Good SMS Auto Reply Message?

Creating an effective auto-reply message is straightforward; however, there are many factors which will make the difference between a warm message that no one can relate to and one that seems very impersonal.

  • Be Concise – The maximum number of characters for text messages is typically 160; that is more than enough space for you to convey your message. Avoid writing an entire paragraph and get straight to the point.
  • Set Clear Expectations – It’s essential to mention whether or not a person will be contacting you back, for example, “Thank you for your inquiry, our team will respond by the end of today.” This is far preferable to nothing at all.
  • Providing Next Step – Make sure you provide something that individuals can do next. Refer to a website, notify them of an upcoming date, give simple instructions on what to expect next, etc.; do not leave them in the dark.
  • Be Human-Like – Using a robotic response, such as “Your request has been received” seems cold and gives the reader little hope. Whereas a friendly response could read “We will send out your volunteer kit by this Thursday,” which sounds like an actual person. You should always strive to create the latter.

3 Real Auto Reply Examples for Nonprofits

After-hours reply: Thanks for reaching out! Our office is currently closed but we will reply first thing tomorrow morning. For urgent help visit [link].

What About Auto Reply on Android or iPhone?

Typical auto-reply solutions offered via Android or Apple will perform reasonably well for use by individuals in driving modes or focus settings but are NOT suitable for Organizations leading to challenges as follows:

• Are every supporter message will be sent an automatic response message

• There are few customization options & you cannot track who has opted out

• Sending messages via a bulk phone like Android and iPhone will limit the ability to manage large volumes of supporter messages 

For Organizations looking to manage/support hundreds or even thousands of supporter relationships, you must use an SMS text platform for businesses versus using text messaging through your phone as if it were a personal cellphone account versus an email marketing service through a Gmail account.

How to Set Up SMS Auto Reply for Your Organization

To set up an SMS autoresponder on a reliable platform takes less than 10 minutes here’s what you need to do:

1. Sign up and receive your unique 10-digit code number for your organization (this will be the number that your supporters will text).

2. Complete the 10DLC registration process in the United States. Every organization sending SMS messages is required by law to register through this process. A good platform will teach you how to go through this process step by step.

3. Select your keyword(s) – select one or more words that are relevant to the message/action you want people to take (for example, “DONATE”, “JOIN IN”, “VOTE FOR ME”, “HELP ME”, “GET MORE INFO”).

4. Write your auto-response message. Keep it as short as possible (preferably less than 160 characters). Be very clear and warm in tone and include the next action step in your message.

5. Use your SMS autoresponder live and test it. Text your keyword(s) from a personal phone before advertising to your supporters to ensure that the message comes through exactly as you intended.

Frequently Asked Questions

What is SMS auto reply?

An SMS auto reply feature allows you to automatically send an immediate text response to any message sent to your phone number. You create the feature one time, and after that, the auto reply system will execute every time it receives a new message or keyword.

How do I set up an auto reply for business SMS?

Signing up with an SMS service provider gives you a dedicated SMS number, allows you to create the keyword that triggers your auto reply messages, and lets you write the reply message you want to be sent. With most service providers, you will be able to start sending automated replies within 10 minutes.

Can I customise auto reply messages?

You can set up multiple automated replies for each keyword so that the auto reply will be different from the other keywords sent to you.

Is SMS auto reply free?

Most SMS service providers include the autoresponder feature as part of your subscription. The cost of using the autoresponder feature is based on the number of messages you send, not based on the fact that the service provider provides you an auto responder.

What is the difference between SMS auto reply and a chatbot?

An SMS auto reply sends a pre-programmed message in response to the keyword triggers. Chatbots use artificial intelligence technology and emulate natural human conversations. For most not-for-profit organizations or campaigns, an SMS auto responder is sufficient. Chatbots tend to be more complex, more expensive, and require more technology than is necessary to perform the services required.

How do I disable auto SMS reply?

You’re able to pause or delete any autoresponder at any time from your business texting platform dashboard. On either iPhone or Android, find your text settings and disable driving or auto-reply features by toggling them off.

Final Thoughts

People feel like you’re speaking directly to them when they send a text to you, and texting is the most trusted method of communication that people can use. When someone texts you and gets nothing back, there is nothing worse than seeing their text disappear into thin air without being answered!

The purpose of having an SMS auto-reply feature is not to take away your ability to have a human-to-human relationship, but rather it gives you an option to provide quality support so that nobody feels like they’re being ignored while you do the actual work of helping them.

To have the SMS auto-reply feature set up is simple. You only need to create the one message and make sure it accurately reflects your organization. Then you let it work quietly in the background because every time you create a trust relationship with someone who sends you an SMS, that relationship grows exponentially!
