3X Your Email Marketing Strategy

25% email open rates mean that 75% of your subscribers do not read your email messages. This could lead to lost revenue. Fortunately, there are 2 simple ways to boost your email marketing strategy fast.

How To Do Even More With Your Email Subscribers

Email open rates are only about 25% (1 out of 4 people) according to MailChimp. That means that 75% of your audiences are not actually reading your email messages. (Of course, higher open rates reduce the percentage of unopened emails.)

Calling and texting campaigns reach more than 95% of your subscribers...directly on their phones. 

An automated calling campaign lets you play your pre-recorded audio message to your contacts within minutes. You'll even know which calls were answered by a human and which calls were answered by a machine.

A mass texting campaign sends a personalized text message to your contacts within minutes as well.

Sigma Voice offers a web-based mass calling and texting service that allows you to get your message to your contacts within minutes. There are no software license fees or phone lines you have to manage.

Both calling and texting have 95% or higher 'open' rates. With almost everyone receiving your message, your revenue and business can grow.

How To Enable Calling & Texting With Your Mailchimp Audiences

Here's the 3 step process below.

Step 1 Opt-in Form

Add a phone number field to the opt-in signup form. Learn more.

Then collect consent to call and text your audience. Learn more.

Here's an example below.

By pressing Sign Up, you consent for [ORGANIZATION] and its authorized vendors to contact you at the telephone number provided for marketing purposes, with the use of automatic calling and texting technology. Message & Data Rates May Apply. Text back STOP at any time to opt-out. Consent is not required to make a purchase.

Step 2 Export Contacts

Follow the instructions to export your audience. Learn more.

Step 3 Import Contacts

In your Sigma Voice account, go to the Groups page. Add a group name then import your exported Mailchimp file.

Once imported, you'll be able to send a call broadcast and text broadcast to your Mailchimp audience with Sigma Voice. If you're interested in trying it for yourself, sign up for your free trial.
