Brevo, Selzy, Maileon, Mailigen, MailWizz, Listamester, Omnisend, The Marketer, WebGalamb: Connect the provider account, select a list and map signup fields to the destination. Some connectors retain older service names in the picker, including Sendinblue for Brevo. CleverReach: Authorize the CleverReach account, choose a recipient group and map the form fields. OptiMonk offers a double opt-in mode that requires selecting a confirmation form. A new recipient can therefore be present but inactive until they click the email. CM Commerce: Select CM Commerce (Conversio) on the campaign, supply the CM Commerce API key and choose a list. Map popup inputs and add fixed field values where useful. The list and mapping can be edited for an individual campaign without removing the account connection. SendGrid: Select SendGrid in the OptiMonk campaign’s integration settings and supply the SendGrid API key. The guide describes adding form subscribers to the mailing list but gives no field-by-field mapping. Confirm any extra attributes inside Marketing Contacts. AWeber: Authorize AWeber in the OptiMonk campaign, choose a list and match the campaign inputs to field identifiers from that list. The mapping options depend on both the form and the selected list. Create the destination field before building a signup around a reader’s preference. Campaign Monitor: Enter the Campaign Monitor API key, test the connection and choose the mailing list in the OptiMonk campaign. To identify form signups, the vendor describes creating a source custom field on the Campaign Monitor list, refreshing the field choices in OptiMonk and selecting it. GetResponse: Connect GetResponse with an API key in the campaign, select the receiving list and map the popup inputs. A static field lets the merchant send a fixed campaign identifier alongside each address. You can change the list for one campaign while keeping the account connection. Klaviyo: Connect Klaviyo, choose a list and map the signup fields. Collected answers follow that mapping; segmentation and follow-up stay in Klaviyo. Mailchimp: Connect Mailchimp, choose a list and map the signup fields. Collected answers follow that mapping; segmentation and follow-up stay in Mailchimp.

Kit: Use Claspo’s webhook integration to send submissions to a Kit form or sequence. The destination ID and request body specify where the subscriber goes and which fields are included. ActiveCampaign, MailBluster, MailerLite, MailWizz, Mautic, Newsletter2Go, Omnisend, Brevo, Zoho Campaigns, Acumbamail, VBOUT, Act-On, Userlist: Send widget submissions to an email platform through its documented integration route. Field mapping can include form answers and submission context where the receiving connector supports those values. beehiiv: Connect a beehiiv API key in the widget integration and select the publication. Map the required subscriber data and use static fields for information shared by everyone submitting that widget. Create the receiving fields in the correct publication first. CleverReach: Connect CleverReach at the widget’s integration step and choose the receiving group. Map the required email field and any additional supported inputs; fixed values can identify the particular signup offer. Inspect both recipient activation and field values in CleverReach. Dotdigital: Connect the widget to Dotdigital, choose the address book and map the contact inputs. System values such as site language and fixed campaign labels can go into separate Dotdigital fields. An address book membership alone does not preserve a visitor’s answer. Iterable: Connect the widget to Iterable, choose the subscriber list and map email plus any supported contact fields. Fixed field values can identify the campaign or language. Check the type of each receiving field when extending an existing Iterable profile. SendPulse: Choose SendPulse in the widget’s integrations, authorize with the account credentials and select the mailing list. Map each input to a SendPulse field and add static values if needed. A fixed language value is useful for a form published on only one language version of a site. SendFox: Claspo documents a webhook setup for SendFox. Configure the contacts endpoint and authorize the request with the SendFox token; map the required email and supported optional parameters in the request. If the signup belongs to one list, verify that membership after submitting. Constant Contact: Authorize Constant Contact on the widget’s Integrations step and select a list. Email is required. Map contact inputs such as name or phone, optionally add browser or language data, and use a static value when every signup should carry the same offer name. GetResponse: Connect the API key, choose the mailing list and map the required email address. Claspo can also transfer widget answers, system fields and fixed values. Its guide points to the list’s API subscription settings for signups that require a confirmation message. SendGrid: Create a restricted SendGrid key with Marketing access as specified in Claspo’s guide, then choose the list in the widget. Map email and any other supported form fields; static values can label the source. This lets a team identify the popup offer on the marketing contact. Klaviyo: Select a list and map each widget’s fields, including custom properties. Email and SMS subscription requests run separately and follow the list’s opt-in settings. Mailchimp: Authorize Mailchimp, choose an audience and map fields; email is required. Select existing groups, add fixed values and enable opt-in confirmation as needed. A Test button checks the setup.

Attentive, Postscript: Send captured contacts to SMS marketing platforms.

MiniCRM, SalesAutopilot: Send new subscribers to the selected destination; provider-specific settings apply. Keap: Connect Keap to the OptiMonk campaign, choose tags that already exist in Keap and map form inputs to contact fields. You can send fixed fields too. Configure the follow-up in Keap using the tag or value the form actually supplies. Ontraport: Use an Ontraport App ID and API key with permission to add contacts. Choose an optional tag in the OptiMonk campaign; if you create the tag in Ontraport, refresh the choices before saving. Submissions add contacts with the selected tag. Salesforce: Connect Salesforce in the campaign and choose the receiving record type. Email maps to the CRM email field; review the suggested mappings for other inputs or leave an input out. A static source value can identify every record submitted by this campaign. HubSpot: Connect HubSpot, choose a list and map the signup fields. Collected answers follow that mapping; segmentation and follow-up stay in HubSpot.

SalesDrive, FluentCRM: Route form submissions into your CRM. Pipedrive: Connect the Pipedrive API token, include Name in the widget and map the supported inputs. You can also create a deal linked to the contact and use a selected component as the deal title. Claspo’s guide excludes transfer to custom Pipedrive fields. Zoho CRM: Authorize Claspo, choose the Zoho CRM module in the widget integration and map the inputs. The guide names Leads and Contacts and requires last_name. It also supports mapping system values and supplying a fixed field such as the enquiry source. Salesforce: Authorize Salesforce from the widget’s integrations and configure the destination and mapped fields. Claspo requires last name in its setup. Map a real surname field for a sales enquiry, then check that the remaining contact and campaign values reach the expected CRM fields. HubSpot: Select a static list and map widget, system or fixed values to contact fields. Email is required; contacts use single opt-in. Active lists are not supported.

Slack: Send team notifications to Slack.
