  • Most important reason is that you can SAVE TIME. And focus on what matters more- Marketing.
  • There will be room for lesser errors as the emails will be sent automatically.

Autoresponder Features:

  • You can’t make out the reason why your subscribers didn’t open a particular email you sent. So with a single click SendX lets you resend the unopened emails with a different subject line.
  • You can auto tag subscribers based on a pop-up they subscribed to or some data they have filled. And then group them to only trigger emails that will interest them.
  • If you think a particular autoresponder sequence is not working for you then you can add or update the triggers and actions as per your liking.
  • To design the emails in the best possible way, SendX provides around half a million royalty free photos so you never run out of options.
  • Every advanced feature takes a backseat when the platform is difficult to use. Therefore prioritizing the user interface, SendX is designed in a very intuitive way which is super easy-to-use.

‍Constant Contact

Autoresponder Features:

  • Constant Contact lets you send a basic welcome email whenever a new subscriber signs up to your list, birthday and anniversary emails to your subscribers, confirmation email on signup, etc, on the premium plan.
  • You can set up your own autoresponder series and select which lists you want to send the emails to. You also have the option to add multiple lists to your autoresponder series.
  • After sending out these emails, it’s important to check whether they are working or not. So you get reports containing the queued contacts, sent, opens, and clicks for all the emails in your autoresponder series. This helps you figure out strategies that perform the best.
  • Of all the emails that the subscribers receive, they usually don’t check all of them due to a number of reasons. And sometimes, an important email might get lost. Constant Contact allows you to trigger an email that automatically resends the missed emails without you having to figure it out yourself.
