Check out Pure360 – from their website it seems like they have both SMS services and integration with Salesforce. I can’t vouch for their service as I’ve never used it, although I did used to live about two minutes from their offices in Brighton! The other option would be something like Infusionsoft. I’m pretty certain that they have SMS functionality, and would be very surprised if they didn’t integrate with Salesforce.
Purchased lists are ineffective, and they impact everyone else who uses Mailchimp, too. If you send emails to a list of people whose contact info you bought, many of the emails will get identified as spam. Some spam filters will flag a campaign if anyone with the same IP has sent spam in the past. When you use Mailchimp, your email is delivered through our servers, so if one person sends spam, it could prevent other users’ emails from reaching inboxes. But by forbidding Mailchimp users from using purchased lists, we increase deliverability for everyone.
Mailchimp makes it easy to design beautiful, personalized email campaigns and automations so you can build and strengthen your relationships with potential and existing customers. And with your online store connected, you’ll collect helpful e-commerce data for your customers—like order history, how much they spent, and whether they’re first-time or repeating customers—so you can send targeted campaigns that direct traffic back to your store and generate more sales.
Find things that encourage people to engage. By tracking the statistics on each of your emails, you'll be able to develop concise reports about what works and what doesn't for your target audience. Take note of the specific days and times for your highest open and conversion rates. Test different tones and subject lines and see what causes your audience to read the blast. Stick to the things that your consumer tends to favor or enjoy and avoid repeating aspects of emails that do poorly according to the stats.
