Hi Laura, welcome and thank you for your question. My name is ***** ***** I am glad to assist you today.
Before I can answer your question, please tell me the following:
Please let me know by replying to me here so that I can help you further.
Thank you for writing back with that information.
Let me address your issues here.
First, yes, you can continue to use your Mac Mail program to send out your emails. However, doing the email blast will 100% put your business email address into blacklist because of spamming. The reason for this is because the receiving email accounts will automatically flag your email account as a spamming account due to sending an email to a lot of people.
There are 2 ways you can do this.
FIrst, you can use a mailing service for free (with limitations). Second, you can use the Mac Mail, but you need to send emails in batches of 30 people only.
With the first option, you can send your email at once for 2000 people without being flagged as SPam.
How do you wish to proceed?
I am very sorry about the confusion. My last question was actually asking as to what procedures do you want to choose to proceed. Do you want to still use your Mac Mail to send out the emails? Or do you want to sign up for such emailing service that can send to 2000 emails at once for free?
