10DLC stands for "10-digit long code,” which is the standard for businesses directly texting their customers in the United States.
To use 10DLC, businesses typically need to register their phone numbers and provide information about their SMS campaigns. This process helps carriers verify the legitimacy of the business and its messaging practices. The timing of this will vary based on the carrier.
10DLC uses standard 10-digit phone numbers that customers are already familiar with, and is specifically designed for businesses to communicate with customers through SMS. There are several benefits for businesses to set up a 10DLC, like:
Compliance: Helps businesses comply with SMS regulations and reduces the risk of message blocking
Deliverability: Helps ensure that messages are delivered to customers’ phones, not filtered out as spam
Consumer trust: Using a registered 10DLC number can increase trust in your brand, since your business won’t appear like a 1-800 number on their phones
Constant Contact offers SMS only, but here is the breakdown between the two types of messaging service:
SMS (Short Message Service)
Text-only content: Limited to plain text messages
Character limit: 160 characters per message
Delivery: Requires a cellular connection to receive messages
MMS (Multimedia Messaging Service)
Multimedia content: Supports images, audio, videos, GIFs, and other media types
Character limit: Up to 1,600 characters per message
Delivery: Requires a data connection to receive messages
Follow these guidelines to collect consent and keep your SMS marketing compliant with regulations:
Remember, The Telephone Consumer Protection Act (TCPA) requires businesses to obtain prior consent before sending marketing text messages to customers, and the CAN-SPAM Act protects consumers from misleading information in commercial messages.
When collecting consent, be sure to include the following information:
Description of the program: Clearly explain what subscribers are signing up for
Shortcode or phone number: Inform subscribers where messages will come from
"Msg & Data rates apply" disclosure: Warn subscribers about potential charges
Message frequency: Let subscribers know how often they'll receive messages
Opt-out instructions: Provide clear instructions on how to stop receiving messages
Link to terms and conditions or privacy policy: Offer transparency about your data handling practices
Contact and support information: Make it easy for subscribers unsubscribe and tell them where to reach out with questions or concerns
Best Practices for Compliance
Send a confirmation text message: Confirm registration and provide initial information
Be mindful of message frequency and timing: Respect subscribers' time and avoid overwhelming them with tons of messages
Keep messages concise and relevant: Ensure messages are valuable and engaging
Personalize messages: Segment your list to send targeted, relevant content
Test and analyze: Monitor delivery rates, click-through rates, and unsubscribes to refine your strategy
Yes! Use our bulk SMS marketing software to schedule your text messages in advance, or include texts as a marketing channel in future automated campaigns.
To improve deliverability across both email and SMS, focus on the following strategies:
Build and maintain a good sender reputation:
Only send emails to subscribers who have opted-in
Regularly clean your email list to remove hard bounces and unengaged subscribers
Use a clear and recognizable sender name
Optimize email content:
Craft relevant and personalized content for your audience
Avoid spam trigger words and excessive punctuation
Use a clear and compelling subject line
Improve email infrastructure:
Authenticate your emails with SPF, DKIM, and DMARC
Use a reputable email service provider with strong deliverability rates
Segment your email list:
Divide your list into targeted groups based on subscriber preferences and behavior
Send relevant content to each segment to improve engagement
Monitor and analyze performance:
Track open rates, click-through rates, unsubscribes, and spam complaints
Use data to refine your email strategy and improve deliverability
SMS throttling is what happens when carriers limit the number of messages you can send each day. Each phone carrier has their own restrictions and regulations, which means your texts are broken into batches and sent to large groups of people over a longer period of time, like a handful of days.
To keep throttling to a minimum, try these tactics:
Segment your contacts:
Break down large lists into smaller, targeted groups
Use tags or create new lists based on subscriber characteristics
Upgrade your SMS plan if necessary:
If you have a large number of opted-in contacts, consider upgrading your SMS plan
Higher-tier plans often allow for more messages to be sent per month, reducing throttling effects
Be mindful of message frequency and timing:
Respect subscribers' time and avoid overwhelming them with messages
Comply with regulations on timing e.g., between 8 a.m. and 9 p.m. in the recipient's time zone)
