Emails triggered by milestones, like anniversaries and birthdays, are fun to get -- who doesn't like to celebrate a special occasion? The beauty of anniversary emails, in particular, is that they don't require subscribers to input any extra data, and they can work for a variety of senders. Plus, the timeframe can be modified based on the business model.
What's the difference between them? One-off communications versus prolonged, email-based interactions. For example, email marketing tools are excellent for one-off communications. You can use these tools for the one time you'd like to send someone an automated email response when they join a subscriber list, on their birthday, or when you promote a new product. But marketing automation tools are better suited for prolonged, email-based interactions. For example, you can use marketing automation tools whenever you want to guide someone from a subscriber list to a product purchase. Or you can send thank you emails or send new product promotions—all without having to lift a finger after the workflow is designed.
Someone voluntarily gives you their email address either online or in person so you can send them emails. They may pick certain types of email content they wish to receive, like specifically requesting email alerts when new blog posts are published. Opt-in email addresses are the result of earning the interest and trust of your contacts because they think you have something valuable to say.
Note: If you want to attach additional files, such as a .pdf, we recommend that you store these files on a cloud storage service, such as Dropbox or Google Drive, and linking to these files within your blast. We do not support file attachments to an email blast as these file types tend to be larger, increasing your chances of triggering spam filters and preventing your blast from reaching your recipients.
