For example, if you set up an autoresponder with an interval of 24 and you receive an email from user@example.com at 8:00 AM on Monday, the autoresponder immediately responds to the message. If, however, user@example.com continues to email you throughout the day, the autoresponder does not send another response for 24 hours after the initial email (in this case, 8:00 AM on Tuesday). If user@example.com emails you again after the 24-hour interval expires, the system sends them an autoresponse.
Last but absolutely not least – Aweber, GetResponse and Vertical Response all have solid Privacy and Anti-Spam Policies in place that are 100% trustworthy as of Dec 2016 at last check. All companies change their policies though so always check the final print (toward the bottom) and make sure you know exactly what you and your clients have “Opted In” for.
We also love how consistent the design of Uber's emails is with its brand. Like its app, website, social media photos, and other parts of the visual branding, the emails are represented by bright colors and geometric patterns. All of its communications and marketing assets tell the brand's story -- and brand consistency is one tactic Uber's nailed in order to gain brand loyalty.

When people talk about email marketing, lots of them forget to mention transactional emails. These are the automated emails you get in your inbox after taking a certain action on a website. This could be anything from filling out a form, to purchasing a product, to updating you on the progress of your order. Often, these are plain text emails that marketers set and forget.
Most importantly, if you hobnob with any other free Autoresponder or paid services and later on if you want a switch to Aweber, it can get difficult to import your list to Aweber unless with double-op-in again! Your list needs to be approved by their import specialists.  So if you are new and starting fresh -- start with Aweber.

I recently had my MailChimp account suspended. One of my sites is in the ‘make money online’ space. It’s a completely legitimate website, but apparently if your emails contain keywords they don’t like, they will suspend you. I would not recommend using them. Contacting support I just get form responses that are completely unhelpful. There’s no phone support- just account termination. Really bad experience. Luckily, this is a very new site- but imagine if you have thousands of emails and they just shut you down without ANY recourse.
