MailChimp.Net - A Mail Chimp 3.0 Wrapper

License

MailChimp.Net is licensed under the MIT license.

Quick Start

Install the NuGet package from the package manager console:

Install-Package MailChimp.Net.V3

Using it in code

using MailChimp.Net;
using MailChimp.Net.Interfaces;

IMailChimpManager manager = new MailChimpManager(apiKey); //if you have it in code

<add key="MailChimpApiKey" value="apiKEY" />
IMailChimpManager manager = new MailChimpManager(); //if you have it in config

Hint: MailChimp needs at least TLS 1.2. To use this library you have to set TLS 1.2 in ServicePointManager

ServicePointManager.SecurityProtocol = ServicePointManager.SecurityProtocol | SecurityProtocolType.Tls12;

Examples

// Instantiate new manager
IMailChimpManager mailChimpManager = new MailChimpManager(apiKey);

Getting all lists:

var mailChimpListCollection = await this.mailChimpManager.Lists.GetAllAsync().ConfigureAwait(false);

Getting 50 Lists:

var mailChimpListCollection = await this.mailChimpManager.Lists.GetAllAsync(new ListRequest
                                                               {
                                                                   Limit = 50
                                                               }).ConfigureAwait(false);

Getting Users from List:

var listId = "TestListId";
await this.mailChimpManager.Members.GetAllAsync(listId).ConfigureAwait(false);

Adding New User To List

var listId = "TestListId";
// Use the Status property if updating an existing member
var member = new Member { EmailAddress = $"githubTestAccount@test.com", StatusIfNew = Status.Subscribed };
member.MergeFields.Add("FNAME", "HOLY");
member.MergeFields.Add("LNAME", "COW");
await this.mailChimpManager.Members.AddOrUpdateAsync(listId, member);

Updating An Existing User

// Get reference to existing user if you don't already have it
var listId = "TestListId";
var members = await this.mailChimpManager.Members.GetAllAsync(listId).ConfigureAwait(false);
var member = members.First(x => x.EmailAddress == "abc@def.com");

// Update the user
member.MergeFields.Add("FNAME", "New first name");
member.MergeFields.Add("LNAME", "New last name");
await this.mailChimpManager.Members.AddOrUpdateAsync(listId, member);

Adding/Removing a Tag From a User

Tags tags = new Tags();
tags.MemberTags.Add(new Tag() { Name = "Awesome Person", Status = "active" });
await this.mailChimpManager.Members.AddTagsAsync(listId, "abc@def.com", tags);

To remove the tag, use "inactive" as the Status.

Status

Full Mailchimp Marketing API coverage (models, interfaces, and logic wired on IMailChimpManager).

Target frameworks: net45, net472, netstandard1.3, netstandard2.0, net10.0

TFM	JSON serializer	Newtonsoft.Json	Microsoft.Extensions.*
`net45`	Newtonsoft.Json 13.0.4	Yes	—
`net472`	Newtonsoft.Json 13.0.4	Yes	10.0.10
`netstandard1.3`	Newtonsoft.Json 13.0.4	Yes	1.1.2 (last line supporting netstandard1.x)
`netstandard2.0`	Newtonsoft.Json 13.0.4	Yes	10.0.10
`net10.0`	System.Text.Json	None	10.0.10

Models use library-local [MailChimpJsonProperty] / [MailChimpJsonConverter] attributes. Legacy TFMs map those through a Newtonsoft contract resolver; net10.0 maps them through System.Text.Json type-info modifiers. API JSON shapes stay aligned across TFMs, and net10.0 has no Newtonsoft dependency at compile time or runtime.
