Marketing always works with current CRM data.
The integration connects your CRM with your newsletter tool in real-time. Here are typical use cases:
Automatically transfer contacts to mailing lists. New contacts from SmartWe are directly synchronized into Inxmail lists. Marketing always works with current data, without manual export from the CRM.
Feed tracking data back to CRM. Opens, clicks, bounces, and unsubscribes appear in the SmartWe contact. Sales sees email engagement before picking up the phone.
Control segmentation with CRM criteria. Sales status, industry, or lead score from SmartWe determine which recipients receive which campaign. Relevance increases, unsubscribe rates decrease.
Synchronize opt-in and opt-out bidirectionally. Unsubscribes in Inxmail also block the contact in SmartWe for further mailings. GDPR compliance across both systems, without follow-up work.
Transfer forms from Inxmail as leads into CRM. Web forms and newsletter registrations automatically land as new contacts in SmartWe. Marketing hands over qualified leads seamlessly to sales.
Automatically maintain distribution lists from CRM views. Views or filters in SmartWe define who belongs in which Inxmail list. Changes to contacts update the lists automatically, without manual adjustment.
The use cases on this page are not theoretical, but implementing them requires experience. You can set up integration and data management yourself through MARINI’s no-code interface, or have our team configure it for you. For implementation in your systems, we work collaboratively with you and your service providers. If you don’t yet have a suitable service provider, we’re happy to recommend an appropriate partner from our network.

CEO at Inxmail
Successful email marketing thrives on interesting and relevant, recipient-specific content. This requires the right content and current data from various sources such as CRM, shop systems, or other platforms. Creating relevant content from data for highly individualized emails is Inxmail’s strength. MARINI provides the necessary data for this, and that’s exactly why the combination of both systems leads to increased revenue and success.

Time is money, duplicate work is wasted money. Every manual list maintenance, every CSV export, every synchronization between CRM and newsletter tool costs time that nobody has. The integration eliminates this overhead. Marketing works faster, sales has better data, you don’t pay for unnecessary staff hours.
98 percent delivery rates are no coincidence. Inxmail is CSA-certified and achieves average delivery rates 11 percent higher than the industry average. This means: More recipients see your campaigns. More visibility, more clicks, more conversions. MARINI ensures that the right contacts land in the distribution lists at the right time.

Segmentation becomes granular, without technical hurdles. You define in SmartWe who belongs in which campaign. Industry, sales status, revenue, lead score: All these criteria automatically control Inxmail lists. Personalization increases, unsubscribe rates decrease.
Lead handover works seamlessly. Form entries from Inxmail automatically land as new contacts in SmartWe. Marketing hands over qualified leads without manual forwarding. Sales follows up faster, conversion rates increase.
