Now that you have designed and tested your email template, you need to make sure it will get there. Here are some of the DO's and DON'Ts for sending out your email blasts the right way.

1. DON'T send out email blasts from the same email server as your company email. You do not want to hurt the reputation of the email server that your day-to-day business relies on. Should your email blast generate complaints, you could see your important business email get blocked and trust me it isn't fun trying to restore that reputation. You should either get a dedicated server or IP address or use a third party email marketing tool for sending all of your email blasts.
2. DO update the SPF (Sender Policy Framework) record for your domain to allow your new dedicated server, IP address or third party to send email from your domain. Most people want the From Address of their email blasts to use the domain of their company. However, unless you update the DNS SPF record for your domain, the deliverability of your email will be affected.

3. DO throttle the initial outgoing email traffic for any new server or IP address you use to send email blasts. The big email providers (AOL, GMAIL, HOTMAIL, etc.) don't like seeing new email servers sending out large volumes of mail right off the bat. Send a small batch of emails around 5000 emails the first day. Then 5000 the next day and then start increasing the volume over time. This will allow your new server or IP to gain a positive reputation allowing for better and better deliverability over time.
4. DON'T use bought or farmed email lists for your email blasts. This should go without saying. Only send email to users who have requested emails directly or have done business with you in the past. The best behavior is to "double opt-in" your users by first sending an email to verify their email address is correct before sending the user actual email blasts. And of course always include a clear and easy way to opt-out of future mailings.
5. DO comply with the FTC CAN-SPAM Act regulations. The CAN-SPAM Act sets guidelines for the sending of email blasts. Violations can result in hefty fines so make sure you follow the guidelines. The full requirements can be found on the FTC's website http://business.ftc.gov/documents/bus61-can-spam-act-Compliance-Guide-for-Business. Some quick guidelines: don't mislead your users, include a mailing address, include an opt-out process and honor those opt-outs within 10 business days.

Follow these DO's and DON'Ts and you'll soon be on the path of email deliverability.
