When creating sending strategies for both Text Messaging and Emailing, it is important to remember to 'warm up' your domain. Immediately sending large campaigns without a warm up period may have several drawbacks such as:

• Email Deliverability Issues: If you suddenly start sending out a large volume of emails from a new or inactive domain, internet service providers (ISPs) may flag your emails as spam. This can lead to a high rate of emails being filtered out or landing in recipients' spam folders, reducing the effectiveness of your campaign.

• Reputation Damage: A sudden surge in email volume can also damage your sender reputation, especially if you're sending emails to recipients who haven't engaged with your content in a while or who never opted in to receive emails from you. A poor sender reputation can have long-lasting effects on your ability to reach recipients' inboxes in the future.

• Unsubscribes and Complaints: If recipients feel bombarded by a sudden influx of emails from your organization, they may be more likely to unsubscribe from your mailing list or mark your emails as spam. This can result in a loss of potential customers and further damage to your sender reputation.

Similar to email campaigns, sending large texting campaigns without a warm-up period can lead to various issues:

• Carrier Filtering: Just like email service providers, mobile carriers have systems in place to filter out spam texts. If you suddenly send a large volume of texts from a new or inactive number, carriers may flag your messages as spam, leading to delivery issues.

• Complaints and Unsubscribes: Recipients who feel overwhelmed or annoyed by a sudden influx of texts may be more likely to complain or unsubscribe from your texting list. This can damage your reputation and hinder your ability to effectively reach your target audience via text messages in the future.
