Q: Can I use SendLoop segments with my OptinMonster campaign?

A: Segments in SendLoop are not associated with subscribers individually. They operate like smart folders where a series of rules determines which subscribers match with the segment. Because of this SendLoop segments cannot be connected to your OptinMonster campaign.

To create segments within your SendLoop list start by navigating to the list overview in your SendLoop account.

Select Create a new segment.

On the right side of the page is a list of current segments for your list and a Create a new segment link. Click this link to add a new segment to your list.

Specify the name, rules, and limit of your segment.

From this page you can give your segment a name, define the rules that determine which subscribers to your list will fit within the segment, and specify a limit to the size of the segment. Once created you can view the subscribers that match your segment by selecting the Subscribers and Reports tab.

Select the Subscribers and Reports tab from your list overview.

Initially this page will show all subscribers to your list. Select the dropdown that displays All Subscribers to open a list of your segments. Select a segment and the list of subscribers will be filtered to show only those that match the rules of the segment.

Select a segment from the dropdown to filter the list of subscribers.

Q: Why am I receiving a “failed to connect” error when trying to connect SendLoop with OptinMonster?

A: This can happen if the API key you’re using has been revoked or if it has been configured to work on only specific IP addresses.

Check the API Settings in your SendLoop account. Make sure the API key you are using matches one of the currently active keys for your account. Also check to make sure there are no Bound IPs associated with your API key. If necessary, try creating a new API key to connect to OptinMonster to resolve this issue.
