Whether you already have a list of subscribers or are starting from scratch, email marketing services can help. All of the services we cover let you add contacts manually using copy and paste or by uploading CSV or Microsoft Excel files. Some integrate with third-party software enabling you to import Gmail and other webmail contacts, Salesforce ($75.00 Per User Per Month and Up at Salesforce.com) and other CRM data, or other software where you might have contacts stored. Depending on the size and location of your list, third-party integration could be key. Verify whether you can export contacts as well (and how easy it is to do so) should you leave the service. Managing users who unsubscribe should also be easy so you're not accidentally contacting anyone who has opted out of your newsletters.
As a growing business, you may also be looking for a CRM solution, and you'll find that the more advanced email marketing services have begun to crossover into CRM. It makes sense: Both types of software deal with managing and communicating with customers. A handful of these services are one-stop shops, either offering both email marketing and CRM out of the box or as add-on services.

There are a couple things we love about this email example from PayPal. Not only is the opening copy clever and concise, but the entire concept also reflects a relatable benefit of using the service. Think about it: How many times have you been in a situation where you went out to dinner with friends and then fussed over the bill when it came time to pay? By tapping into this common pain point, PayPal is able to pique the interest of its audience. 
Media is being consumed in ways that we could never have envisaged back at the inception of email. It's our job as email marketers to evolve with these changes by providing content that fits seamlessly into increasingly busy schedules and onto an increasingly varied number of devices. In turn, we can reap the rewards by successfully encouraging higher levels of engagement with the emails we're sending.
When that’s the case, use small image files. Many email marketing service providers recommend images no larger than 1MB. Some email providers block images from senders that aren’t in a subscriber’s contacts, so you should always add alt text for any images. This ensures recipients know what an image is and they can click to view the image if they’re interested.
First of all, BuzzFeed has awesome subject lines and preview text. They are always short and punchy -- which fits in perfectly with the rest of BuzzFeed's content. I especially love how the preview text will accompany the subject line. For example, if the subject line is a question, the preview text is the answer. Or if the subject line is a command (like the one below), the preview text seems like the next logical thought right after it:
Transactional emails (like an order confirmation) are best sent immediately after the purchase is made. Lifecycle emails—which are sent based on specific behaviors a customer exhibits—require a little more testing to get right. The best time to send an abandoned cart email, for example, can vary based on the reason for abandonment and your strategy for recovering those orders.
Give people a way to avoid more emails about the same offer. If you do a concentrated promotion for something, you might send lots of emails about it in a short time. Give people the option to avoid future emails about the offer. Just add a link to the end of the emails (e.g., “If you’re sure you’re not interested in [ offer ], click here, and I won’t send you any more emails about it this year.”). That way you won’t annoy people who aren’t interested in the offer now. You could argue that some of them might buy if they saw all the emails. Well, if you’re only interested in this month’s sales, send as many emails as you can. I just assume you want to have someone left on your list for next month.

A very popular email marketing solution, Campaign Monitor provide its users with an easy-to-use drag and drop email builder as well as a drag-and-drop segmenting tool (to create different campaigns with different contacts). Using their email template, users can customise emails to fit their brand. This email marketing tool also offers A/B testing to optimise test subject lines, sender details and email designs.
Keep the subject line and pre-header short: The subject line is crucial. Keep it short so the reader knows exactly what the email topic is about. And the pre-header text (also known as snippet text), don’t let it go to waste by using “To view this email in your browser…”. Instead, summarize the email or include a call to action (i.e., Use “FREESHIP” to get free shipping).
