I use Ratepoint because they also offer a review (testimonial) widget I have posted on my site. Ratepoint has a promotion that offers free mailing list service forever if your list is 125 or less. Obviously most of us will want more than 125 folks reading our newsletters but it’s a good start. Good templates, tracking and definitely awesome support.
You will benefit from a range of tools when you use the email marketing service from Benchmark, with features such as the ability to add links, social media, and other interactive features to your marketing materials. You can also create surveys and send them out with the Benchmark Email marketing system, and this is part of the package which is not always the case with some competitors. - Joseph Raspolich
Infusionsoft is a fully functional CRM and marketing solution created for small and medium-size businesses. Comparing it to Mailchimp or AWeber is like comparing a Lamborghini to a VW Golf. It provides highly advanced features for list segmentation, lead scoring, and marketing automation. On top of all that, you can integrate all of these features with your optin form using Infusionsoft Tags + OptinMonster.
We’ve changed email marketing from iContact to MailChimp and, just now, Aweber. We changed from iContact to MailChimp to cut costs. We then switched to Aweber because Mailchimp will not allow you to start an Autoresponder series on an imported list PLUS, as you mentioned, Aweber has much more robust measuring/management tools. However, people should be aware that Aweber requires imported subscribers to opt-in all over again.
Think about implementing referral links to incentivize your subscribers to spread awareness about your brand, too. Referral links allow your current customers to promote trackable links for your business. In exchange for sending new paying customers your way, you can give them incentives like discounts, coupons, vouchers, cash, prizes or redeemable points.
